The Martian moon Phobos is believed to be very similar to C- and D-type asteroids, and it has been suggested that it also has the properties of a carbonaceous chondrite.
Phobos and Deimos are believed to be captured moons.
It is believed that Phobos was most likely a captured asteroid.
The moons Phobos and Deimos of planet Mars are believed to be captured asteroids because of their closeness to the Asteroid Belt. And Triton, one of Neptune's moons, is also believed to be captured by the Kuper Belt. But if you're asking about the Earth's moon, it's not.
No. An asteroid can get captured by an asteroid and become a moon, but not the moon. Our moon is too large to be considered an asteroid.
Phobos and Deimos are believed to be captured asteroids because of Mars close proximity to the Asteroid belt and their "asteroid" appearance.
The second theory says that the moon is a captured asteroid.
No. It is an irregularly-shaped satellite of Mars, believed to be an asteroid captured by the planet's gravitational field.
The moons Phobos and Deimos of planet Mars are believed to be captured asteroids.
That would apply to just about any small moon. Larger moons will have a round shape.
This is false.
That is was a captured asteroid, it broke away from the earth after a huge impact, that it formed at the same time as the earth.
The first confirmed case of an asteroid orbiting another asteroid is the asteroid Ida which is orbited by a smaller asteroid orbiting it called Dactyl; other asteroid moons have been found since.
