In the solar system, there is a lot of distance between Mars and Jupiter. The main asteroid belt is in this area.

What is the reason a planet did not form between Mars and Jupiter?
Select one:

1. Mars has two very fast-moving moons. These moons prevented a planet from forming in the area.

2. This area gets a lot of stellar wind from the sun. Planets cannot form in areas that get a lot of stellar wind.

3. Planets can only form close to the sun or far away from the sun. This area is a region where planets cannot form.

4. Jupiter’s gravity affected this area so much that no planet could form there.
