How big is Mars?

Mars is 6,800 kilometres

Introduction: The Mysteries of Mars

Have you ever looked up at the night sky and wondered about the distant red dot glowing among the stars? That’s Mars, the fourth planet from the Sun, a world of mystery and intrigue that scientists are keen to explore. Known as the “Red Planet” because of its reddish appearance, Mars has captured our imagination for centuries. Let’s dive into the fascinating world of Mars, especially its size and how it compares with other celestial bodies.

The Size of Mars: A Closer Look

Mars is not the largest planet in our solar system, but it’s not the smallest either. Mars has a radius of 3,389.5 kilometers, or 2,106 miles. To give you a better idea, that’s about half the size of Earth! If Earth was the size of a basketball, Mars would be about the size of a soccer ball.

  • Mars’s diameter: 6,779 kilometers (about 4,212 miles) - Earth’s diameter: 12,742 kilometers (about 7,918 miles) Mars might be smaller, but it has a lot of interesting features that make it stand out.

Mars Compared to Other Celestial Bodies

To understand Mars’s size better, let’s compare it to some other objects in space:

  • Mars vs. Moon: Our Moon is only about one-third the size of Mars. If Mars was an apple, our Moon would be roughly the size of a plum. - Mars vs. Venus: Venus is our closest neighbor and is often called Earth’s twin because of its similar size. However, Mars is only about half the size of Venus. - Mars vs. Mercury: Mercury, the smallest planet in our solar system, is smaller than Mars. Mars is about twice the size of Mercury.

Unique Features of Mars

Despite its smaller size, Mars is home to some of the solar system’s most incredible geological features:

  • Olympus Mons: This is the largest volcano in the entire solar system, standing at a whopping 13.6 miles (22 kilometers) high, which is nearly three times the height of Mount Everest, Earth’s tallest mountain! - Valles Marineris: One of the largest canyons in the solar system, it stretches over 2,500 miles (4,000 kilometers) long, which is about ten times longer than the Grand Canyon.

Wrapping Up

Mars, the “Red Planet”, might be smaller than Earth, but it’s packed with unique features that make it a fascinating place to study. From its towering volcanoes to its vast canyons, Mars teaches us that size isn’t everything. As we continue to explore Mars, who knows what other secrets this intriguing planet may reveal?

Smaller By Category
Ganymede
Ganymede is the largest moon in the Solar System. It orbits Jupiter and was discovered by Galileo, which makes it a Galilean moon. Also, Ganymede is not to be confused with Ganymed, which is an asteroid whose name doesn't have the final "e"!
Titan
Titan is Saturn's only large moon. It has a very thick atmosphere, which is mostly made up of nitrogen. Earth's atmosphere is also mostly nitrogen. Titan has seas of liquid methane. (It's around -180 °C.) There's even a continent called "Xanadu".
Mercury
Mercury is the closest planet to the Sun. It has no atmosphere. During the day, temperatures reach 430 °C, but at night, the temperatures fall to -180 °C. One Mercurian year is 88 Earth days.
Larger By Category
Asia
Asia is the Earth's largest continent, holding over four billion people – over half of the world's population. Africa is the second most populous continent, but only has one billion people.
Sirius B
Sirius B is a white dwarf. It's barely bigger than the Earth! It's usually pretty hard to see because it is hidden by Sirius A's blinding light. Sirius B is known as "The Pup".
Venus
There was a time when Venus and Earth were thought to be sister planets. That isn't true at all! Venus's surface temperature is always above 450 °C, because its atmosphere, which is mostly carbon dioxide, traps the Sun's heat!
