## What would happen if Mars was Earth sized?

Computer models of a giant impact of a Mars-sized body with Earth indicate the impactor’s core would likely penetrate Earth and fuse with its own core. This would leave the Moon with less metallic iron than other planetary bodies.

## How far is Mars from Venus?

Distance Between Planets

From To AU
Venus Uranus 18.49
Venus Saturn 8.80
Venus Jupiter 4.48
Venus Mars 0.8

What if Mars was our moon?

Mars is about double the size of the Moon. If Mars were to become our only natural satellite, things in this part of the Solar System would change. For Mars, taking the place of the Moon would mean temperatures on the red planet would rise from their current average of -60°C (-80°F). Its polar ice cap would melt.

### What is the angular diameter of Mars when it is 1.0 108 km from Earth Mars’s diameter is 6.8 103 km?

(b) It would take this object 1000 yr to move 360°: 360°/1000 yr = (360 × 60′)/ 1000 yr = 21.6′/yr. So, to move 1′ across the sky would take it a time = 1′ / (21.6′/yr) = 0.046 yr = 17 days.

### Which planet is about 10 times as far as Earth is from the sun?

Saturn: The Basics Distance from the sun: About 900 million miles, nearly 10 times as far as Earth is from the sun. Year: About 29 Earth years. Day: About 10.7 Earth hours. Diameter: About 72,000 miles, nine times the size of Earth.

What are the similarities and differences between Venus and Mars?

But both are visible with the unaided eye, and two of the brightest objects in the night sky. Venus orbits at an average distance of only 108 million km from the Sun, while Mars is an average of 228 million km. Venus gets as close to Earth as 38 million km, and Mars gets as close as 55.7 million km.

#### What is the diameter of Venus compared to Earth?

Its diameter is 12,104 km, which is 95\% the diameter of Earth. Mars is much smaller, with a diameter of only 6,792 km. And again, in terms of mass, Venus is almost Earth’s twin. It has 81\% the mass of Earth, while Mars only has 10\% the mass of Earth.

#### What would happen if Venus orbited Mars?

Venus has a very high albedo, meaning that the planet reflects roughly 75\% of the radiation it receives. The stifling temperatures at the planet surface are due not to a high level of sunlight but to the thickness of the atmosphere. Conditions on the planet may therefore not be immediately affected if Venus orbited in Mars’s cooler location.

What would happen to Venus’s atmosphere in the long term?

The surface of Venus captured from the former Soviet Union’s Venera 13 spacecraft, which touched down in March 1982. Image credit: NASA. Exactly what would happen to Venus’s 90 bar atmosphere in the long term is not obvious. It may be that the planet would slowly cool to more temperate conditions.
