Millions if not billions of years ago asteroids helped create the planets that are in our solar system today. The Earth probably could handle larger moons however our moon was a single large asteroid that struck the Earth. The Earth then took the asteroid as its satellite.

Is it rocky on Neptune?
No, indeed. All of the planets farther out than Mars are gas giants. They are much, much larger than Earth, for instance, and are composed of various gases. There may be a rocky center core in the gas giants, but not on the surface. The moons of most of the gas giants are rocky . . . some have volcanoes - some are covered with ice.
Why are mars moons and the smaller moons of the outer planets an irregular shape while the larger moons discussed in the exploration are spherical?
Mars' moons are much smaller than, for example, Earth's Moon, or the larger moons of Jupiter. A large moon will have a larger gravity, which will tend to pull the moon together into a spherical shape.
Which planet is bigger europa or earth?
Europa is not a planet; it is one of the moons of Jupiter. Earth is much larger than Europa.
How is Earth's moon different then moons of other planets?
Earth's moon is very large in proportion to its planet. It is just over one quarter of Earth's diameter. While several moons in the solar system are larger than our moon, they orbit much larger planets.
Why are gas giants called that?
They are giant - much larger than Earth - and they consist mainly of gas.
What are the mian characteristic of the gas giants?
they are much larger and more massive than earth and they do not have solid surfaces.
Is a martian moon smaller than earth?
Yes, much smaller. Earth is much larger than even the largest moons in the solar system. The moons of Mars are tiny as far as moons go. Phobos has a mean diameter of 22 km (13.6 miles) while Deimos has a mean diameter of 12 km (7.5 miles). So the Martian moons are smaller than some cities.
Which planet is the same size as earth with no moons?
No planet! However, Venus has no moons and is not much smaller than Earth.
Are stars really little moons?
No. Stars are much larger than planets or moons. Stars are suns, some larger and brighter than our own.
How much moons are there around earth?
The earth only has one moon
What is unusual about the size of the moon?
The moon is unusually large in proportion to Earth at just over a quarter its diameter. While several moons in the solar system are larger than ours, they orbit much larger planets.
How many earths can fit in the moon?
Lots of articles say you can fit 49 or 30 whatever moons in earth but this is not true because the moon is 24.2% the size of earth so about 4 moons. Lots of science shows like the universe on history channel say 4 moons can fit in earth. But the Earth is much denser so about 45 moons would equal the mass of the earth. EDIT: The diameter of the moon is approximately 24.2% the diameter of Earth, but this does not necessarily mean that the volumes are in this ratio. Therefore, you cannot conclude that there are about 4 moons. If no volume was left unused, approximately 49 moons could fit into the Earth (this is not possible in reality as there would have to be empty space to be able to fit the moons into the Earth. So the actual amount of moons that could fit into the Earth is going to be a little less than 49 moons (36 according to some sources).
