How does the size if Mercury's core compare to Earth's core?
Proportionate to it's size, Mercury has a much larger core than earth, although it's composition is believed to be similar. There are a great many enigmatic aspects to Mercury that are just starting to be explored.
If you stood on th surface of mercury what colour would the sky be?
The atmosphere of Mercury is so weak the sky has very little color. It would be dark outside during both daytime and nighttime. (The sun would appear about 3 times larger than it would here on Earth.)

Jupiter's largest Moon is Ganymede. It is slightly larger than the planet Mercury. As the Earth is more massive than Mercury, the answer is no.
Why do meteoroids hit Mercury but not other planets?
Meteoroids are small enough that they will usually disintegrate when they enter a planet's atmosphere. Mercury has no atmosphere to speak of, and so it is not shielded in this way. Larger asteroids still do strike other planets.
What moon larger than Mercury and has atmosphere?
Titan, Saturn's largest moon, is the only moon in our solar system with its own atmosphere. It (and Jupiter's Ganymede) are both larger than Mercury. I believe the surface gravity on each is less than that of Mercury, however. Not absolutely certain of this. I saw Titan for the first time earlier this year, through our astronomy club's new 14" telescope.
What moon of Jupiter is bigger than mercury?
Both Titan and Ganymede are larger than Mercury and Pluto.
Which rocky planet has only thin atmosphere?
Mars, It has a thin atmosphere of carbon dioxide. Earth and Venus have relatively thick atmospheres due to their larger size, while Mercury's mass is not large enough to sustain any stable atmosphere.

Which planet doesn't have a gravity to support an atmosphere?
Mercury and Mars are the only planets without an atmosphere, not including dwarf or exoplanets. This isn't necessarily due to a lack of gravity, however, because Mars is larger than Venus, which definitely has an atmosphere, and gravity is linked to mass.
Which planet Titan is larger than Mercury?
Titan is larger than Mercury, but Titan is a moon, not a planet.
