how was this planet formed
No. The moon formed after a planet-sized object collided with Earth.
Mercury
mercury
It captured gas.
No planet ever existed where the asteroid belt is. The mass is insufficient for a planet to have formed from all that debris.
Natural satellites are formed through various processes, such as gravitational capture, co-accretion, or collision. For example, moons can be captured in a planet's gravitational field, formed alongside their planet from the same material, or created through the collision of a planet with another celestial body, resulting in debris that forms a moon.
look some where else you bum
i believe mercury
approximately, yes
It is believed, hypothetically, that primitive life may have formed extra terrestrially on the planet Mars.
Because that is how the Solar system formed.
Nobody invented Jupiter. It formed naturally.
