Size can mean different things.
Mars is just over half the diameter of Earth, and has only 11% as much mass.
These are the most common "size" ratios (mars/earth):
Mass: 0.107 (10.7%)
Mars has 11% of the mass of Earth.
Volume: 0.151 (15.1%)
Mars has 15% of the volume of Earth.
Mean Radius: 0.532 (53.2%)
Mars has a radius about half the radius of Earth.
The equatorial diameter of Mars is 6792 km (4220 miles).
The equatorial diameter of Earth is 12756 km (7926 miles).
Really small. 3.68x10^37% in scientific notation.
Mars is about 53% the size of Earth. This means that if you were to represent the size of Mars compared to Earth as a fraction, it would be 0.53/1.
The gravity of Earth is 2.6 times that of Mars.Mars's gravity is 38% of Earth's gravity.
The gravity on Mars is 0.379 that of Earth.
The surface gravity on Mars is about 37% or 3/8 that on Earth.
No, not particularly, because the gravity on mars compared with earth is 38%, which isn't much.
Really small. 3.68x10^37% in scientific notation.
Mars can be compared to Earth, because they both have numerous similarities.
Mars is 6,786 Km. in diameter. Big is a relative term. It is big compared to its moons but small compared to the sun
Mars is only about half the diameter of Earth.
A year on Mars is equal to 687 Earth days. That is about 2 Earth years.
Some advantages of Earth compared to Mars include a breathable atmosphere, liquid water in abundance, a diverse ecosystem that supports various forms of life, and a stable climate that allows for sustained human habitation. Additionally, Earth has a stronger magnetic field that protects the planet from harmful solar radiation.
Mars is about 53% the size of Earth. This means that if you were to represent the size of Mars compared to Earth as a fraction, it would be 0.53/1.
