What else can I help you with?
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.
What is generally true about the number of moons of owned by terrestrial planets vs gas planets?
The total number of moons owned by the terrestrial planets is three, and that's a stretch, as one of Mar's moons is almost certainly a captured asteroid. The gas planets have scores of moons among them, mostly because they are much larger, hence have much greater gravity, and attract more moons among them.
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.
