Earth or Planet Earth (also called the Real World) is an expansive planet that features a wide variety of people, cultures, and ecosystems. Although Earth in the Mario series is supposed to be the actual planet Earth, like other nonfictional concepts that have entered the series, the Earth that appears in Super Mario acts as a comic, satirical version of the real life subject. It shares many similarities to Mushroom World, including several species of plants and animals. The relationship and distinction between the two worlds is sometimes vague, but they are sometimes portrayed as being linked to one another through Warp Pipes. The planet has been referred to as the "Real World" by citizens of the Mushroom Kingdom. It is the third planet from the Sun.
Planet Earth is featured as the setting of the Mario & Sonic series, in which species from the Mushroom World are also present on Earth for the games. It also is the setting of Mario is Missing!, in which Luigi must travel around the globe on a hunt to rescue Mario and save the world.
Earth is a vast planet that includes plains, mountains, oceans, and deserts. The planet is divided by seven continents surrounded by vast oceans. The planet is orbited by a single moon.
 Lands of Earth
Earth is organized into seven continents whose borders are based on geographical features rather than political boundaries. Continents are not necessarily separated by water. With the exception of Antarctica, each continent is further subdivided into countries, political bodies ruled by a government. Several countries are in more than one continent. The subdivisions of countries vary, but every country has population centers such as towns or cities.
Africa is home to both sandy deserts and lush rain forests. Its nations include Egypt, Nigeria, South Africa and Kenya. Humans and a variety of exotic animal species inhabit this continent. In the The Adventures of Super Mario Bros. 3 episode 7 Continents for 7 Koopas, Kooky went to Africa and turned all the animals there into stuffed animals.
Antarctica is a large icy, ferociously cold desert continent located at the southernmost point of the planet populated by penguins. It is the only continent that does not have specific countries ruling portions of it. In 7 Continents for 7 Koopas, Big Mouth is sent here. He builds an Abominable Snowkoopa that goes around scaring penguins. In Mario is Missing!, Bowser attempts to melt Antarctica in a plot to flood Earth.
The largest continent, Asia is home to a variety of countries, including Japan and China. The Great Wall of China is one of the continent's most famous landmarks. China's nation capital, Beijing, was the location of the Olympic Games in which Mario, Sonic the Hedgehog, and others competed during the events of Mario & Sonic at the Olympic Games. In 7 Continents for 7 Koopas, Bully is sent here. He does graffiti on the Great Wall of China.
The smallest continent on Earth, Australia is home to humans and a variety of animal species, including Kangaroos. Alligator Dundee originally lived on this continent. It is often referred to as "down under" due to its location in the southern half of the planet. In 7 Continents for 7 Koopas, Cheatsy is sent here. He turns almost all the humans into kangaroos, while Cheatsy turns one into a shrimp.
Europe shares a land mass with Asia, separated from it by the Ural Mountains. Famous for its varied culture and large role in Earth's history, Europe is divided into countries such as France, the Netherlands, the United Kingdom, Russia, and Italy. Famous cities include Paris and Venice. Europe is mainly inhabited by humans. In 7 Continents for 7 Koopas, Kootie Pie is sent to Europe. She turns famous paintings into paintings of her (Mona Kootie Pie, etc). England's capital city, London, was the main setting for Mario & Sonic at the London 2012 Olympic Games, where the 2012 Summer Olympics took place.
North America is the location of the United States, Canada, and Mexico, among other nations. The United States is home to many famous and influential cities and other locations, many of which were featured in The Super Mario Bros. Super Show! and The Adventures of Super Mario Bros. 3. These include Brooklyn, which is sometimes depicted as the place where Mario and Luigi used to live, Washington, D.C., the nation's capital, Hawaii and the Kennedy Space Center. The Canadian city of Vancouver is the location of the game Mario & Sonic at the Olympic Winter Games.
A largely tropical continent, South America is famous for the Amazon Rainforest. Countries include Argentina, of which Buenos Aires is the capital. "7 Continents for 7 Koopas" portrayed a part of South America's human population as primitive, spear-chucking hunter-gatherers. In 7 Continents for 7 Koopas, Hop is sent to the southern of the Americas. He turns the Amazon Jungle into a parking lot.
 Extinction of the Dinosaurs
The Super Mario Bros. film features an introduction that outlines the rule and extinction of the dinosaurs on Earth. Dinosaurs used to live the good life, superior to the small mammals who also inhabited the planet, until one day a gigantic meteor struck the planet, destroying the dinosaurs. They were divided into 3 periods. However, the narrator then asks the audience to consider a "what-if" scenario that paves the way for the remainder of the film.
As the plot of Super Mario Bros. is a "what-if" scenario, the applicability of this piece of Earth's history to the rest of the Super Mario series is unknown. Nintendo has yet to comment on this matter.
 Super Mario Bros. Plumbing
In some representations of the Mario brothers, including The Super Mario Bros. Super Show!, Mario and Luigi lived on Earth (sometimes referred to as the "Real World") and ran a Brooklyn plumbing business: Mario Brothers Plumbing, but later arrived in the Mushroom Kingdom via a Warp Pipe. Many of the brothers' relatives lived on the planet as well, including Mama Mario and Papa. Mario and Luigi's plumbing business was moderately successful.
How the brothers came to leave Earth in these portrayals of them is somewhat inconsistent. As revealed in "The Legend," the brothers left Earth for the Mushroom World upon hearing a call for help through the pipes in Mario Brothers Plumbing. According to the introduction to The Super Mario Bros. Super Show! and "Toddler Terrors of Time Travel," the brothers happened upon a Warp Zone to the Mushroom World while performing a house call, and were sucked down. This second explanation was later modified through the power of Ludwig von Koopa's Time Travel Tube, but no major changes were made to Earth's history.
The games Super Mario World 2: Yoshi's Island, Yoshi's Island DS, and Mario & Luigi: Partners in Time have all confirmed that Baby Mario and Baby Luigi lived in the Mushroom World. This complicates things as it somewhat conflicts with the explanation that Mario and Luigi are from Brooklyn.
It is possible that these games were retcons on the previously established story line. However, one could speculate that its possible that the brothers migrated to Earth sometime after these games, before again returning to the Mushroom World as adults. Another explanation may simply be that there is no one story on the brothers' history, and that various stories exist within self-contained universes, determined by how the particular writers or game designers wish to portray them at the time.
 Other Appearances
In Mario Party 7, while all the Boards exist in the Mushroom Planet, the Mushroom Planet (when depicted in the game) resembles Earth.
Also, Wario refers to the area below the Awazon as "deep within the Earth" in the manual of Virtual Boy Wario Land. It is unknown if he is referring to the Mushroom Planet as "Earth", calling the Awazon area "Earth", or merely referring to the soil of the Awazon.
In Mario Kart Wii, Earth appears while the player is waiting in the Nintendo Wi-Fi Connection and in the Rainbow Road course of the Special Cup. The planet is located in the background of the course, underneath the track. If the players accidentally fall off the course, they will fall to the void by the gravity of the planet, instead of floating in space.
In Mario Kart 7, like Mario Kart Wii, Earth appears while the player is waiting in the Nintendo Wi-Fi Connection.
 Appearances in Other Media
In The Super Mario Bros. Super Show!, Mario and Luigi often try to find their way back to Brooklyn (their hometown in the cartoon series) usually via a Warp Pipe. Towards the end of the series, the Mario Brothers decide to stay so that they can protect Princess Toadstool and the Mushroom Kingdom. Additionally, the live action sequences take place in Brooklyn. The first and last parts of the Super Mario Bros. film are also set in Brooklyn.
Additionally, in The Adventures of Super Mario Bros. 3, many episodes featured characters using Warp Pipes to travel back and forth between the "Real World" (Earth) and Mushroom World. In the episode "7 Continents for 7 Koopas", Bowser assigns each of his seven Koopalings to take over one of the Real World's continents.
Notably, after all the trouble is undone, a screen is shown with non-native animals in the Australia section.
During the events of the Club Nintendo comic "Donkey Kong in: Banana Day 24", aliens erroneously took Earth for a giant coconut, and since they adored this kind of fruit, they took the planet with them, pulling it away from the sun. This resulted in a sudden drop of temperature all over the planet. When Donkey Kong and some of his friends talked to the aliens, they returned Earth back to its original position.
In the comic "Die Jagd nach dem Nintendo 64: Krawall im All", from the same magazine, Mario and Luigi traveled through space in search for a new spaceship. They finally found it on Earth (which Luigi referred to as "Planet Terra").
 "Dino World"
In the Super Mario Bros. live-action film, an alternate, unnamed version of Earth is revealed to exist; this parallel Earth was brought into creation when a meteorite struck the true Earth, causing spatial and dimensional disturbances, resulting in the creation of the alternate Earth, which the dinosaurs, at least those who weren't killed, and a few other creatures were flung to.
On this Earth, various types of dinosaurs evolved into humanoid creatures, though some, such as Yoshi, seemed to have retained their reptilian forms. Aside from one rundown city, Dinohatten, this Earth is a desert wasteland, lacking various resources.
