Mercury - Is it a core?
Apparently Mercury is so dense...it is believed to be 2/3 iron.
1. Is there any evidence to suggest that Mercury might not have started out in its present location? (e.g. nature of orbit) 2. Now for the dumb question: Is there a link between Mercury and the Asteroid belt? 3. What do u feel about a chocolate bar called Mercury? - Curry flavoured one end and RADOX BLUE on the other. |

As you get closer to the Sun, it gets hotter and so the lighter elements and compounds (and those that form gasses at lower temperatures) tend to get boiled off. 1.

I feel glad they aren't sold in Australia. |

Now for the dumb question: Is there a link between Mercury and the Asteroid belt? I also have always wondered about the large eccentricity of Mercury's orbit as well as its high density. It has been theorized that the Moon was created when a "Mars sized" planet had a grazing collision with the Earth billions of years ago during the early history of the solar system. The planet that grazed Earth would have probably had its outer layers ripped away leaving a jumbled up, dense inner core, and nobody knows what happened to that planet after the collision. Perhaps the loss of mass / momentum added to the billiard ball effects of orbital mechanics may have created Mercury in its present orbit? |

Mercury has all those craters. Does anyone know what the temperature
might be of a crater that's in the shade.? Bert |

In message , Double-A

Bert Well, the craters near the poles contain something shiny, which is suspected to be ice. There are places in those craters where the sun never shines. NASA has just announced a probe will be sent in 2012 to take a more extensive survey of Mercury and examine more closely those polar craters, which seemingly contain ice. The discovery of ice on the Moon makes it more likely. Don't you have that backwards? The reports of ice at the Moon's poles have been questioned (see http://www.universetoday.com/am/publish/no_ice_moon_south_pole.html, for instance), while the Mercury results still seem quite strong. -- What have they got to hide?
