How long is Mars equatorial diameter?
4,222 miles
At its equator, Mars has a diameter of 4,222 miles (6,794 km), but from pole to pole, the diameter is 4,196 miles (6,752 km). Mars’ radius is, of course, half of planet’s diameter.
How large is Mars compared to Earth using the equatorial diameter?
Mars (diameter 6790 kilometers) is only slightly more than half the size of Earth (diameter 12750 kilometers). Note the difference in color between the two planets. Almost 70% of Earth’s surface is covered by liquid water.
Which planet has an equatorial diameter of 120 536 km?
Saturn is classified as a gas giant. The diameter at its equator is about 74,898 miles (120,536 kilometers). Since the planet has no solid surface, its diameter is measured at a level equal to the pressure at sea level on Earth. Saturn’s diameter is more than nine times larger than Earth’s.
What is Mars size compared to Earth?
Size and Distance With a radius of 2,106 miles (3,390 kilometers), Mars is about half the size of Earth. If Earth were the size of a nickel, Mars would be about as big as a raspberry. From an average distance of 142 million miles (228 million kilometers), Mars is 1.5 astronomical units away from the Sun.
How does Mars compare to Earth?
Mars is about half the size of Earth by diameter and has a much thinner atmosphere, with an atmospheric volume less than 1% of Earth’s. The atmospheric composition is also significantly different: primarily carbon dioxide-based, while Earth’s is rich in nitrogen and oxygen.
What is the diameter of Mars compared to Earth?

What is the diameter and mass of Mars?
Its diameter, at 3,474.8 km, is one-fourth the diameter of Earth; and at 7.3477 × 1022 kg, its mass is 1.2% of the Earth’s mass. It’s mean density is 3.3464 g/cm3 , which is equivalent to roughly 0.6 that of Earth.
What is the equatorial diameter of Venus?
12,104 km
Venus/Diameter
Venus: Venus is often referred to as Earth’s “sister planet“, and not without good reason. At 12,104 km (7521 mi) in diameter, it is almost the same size as Earth.
How large is Mars?
At its equator, Mars has a diameter of 4,222 miles (6,794 km), but from pole to pole, the diameter is 4,196 miles (6,752 km). Mars’ radius is, of course, half of planet’s diameter.
