The sun is very far away, it takes light form the Sun 8 minutes to reach the Earth. At this scale the difference in height between the top of a mountain and the beach is insignificant, both places receive the same amount of light/heat form the Sun.
What makes the mountain top cold is vertical variation in temperature caused by the earths atmosphere. As you go up form sea level, the air cools by about one degree Centigrade for every 300 feet you go up. Thus as you are surrounded by colder air, it is colder on the top of a mountain - (or looking at it another way, the mountain pokes up into a region of colder air).
Look at the link I will place below for more information on air temperature.
if the asteroid is closer to the sun does it go faster or slower
as you get closer it gets warmer and as you go farther away it gets colder
As you go higher in the atmosphere, the air becomes less dense and is unable to trap heat as effectively. This causes the temperature to decrease, despite being closer to the sun. The warmth comes from the Earth's surface absorbing sunlight, rather than from proximity to the sun itself.
Mercury is closer to the Sun than any other. Venus is the second planet from the sun and has a temperature that is maintained at 462 degrees Celsius, no matter where you go on the planet. It is the hottest planet in the solar system.
Two main reasons, first is closer distance, means it has less distance to go around. Secondly, the closer to the sun, the heavier its gravitational pull. Think of it rotating faster because the sun pulls it faster than us.

The top of a mountain is closer to the sun than the land around during the day it, but given that the sun is more than 90 million miles away, that difference is negligible. The higher you go up in the atmosphere, the colder it gets. This is because the air at high altitudes is less compressed than the air at low altitudes. When a gas is decompressed, it cools.
You can certainly go closer than we are now, but the closer you get to the Sun, the hotter it will get, and the more special protection would be required.
Roughly speaking, as you go farther away from the Sun, planets get colder.
Gravity. The closer a planet is to the sun, the faster it must move to keep from falling into the sun. So note; the closer in; the smaller the orbit AND the faster the speed.

The Moon goes in front of the Sun. The Moon is closer to the Earth than the Sun, so when both the Moon and Sun can be seen from the Earth (i.e. they are both in the same direction) the Moon will always be closer.
since it is closer to the sun it gets around the sun faster cause it has less of a rotation to go around Mercury only has 88 days in a year cause its closer but since were farther we have 365 days in a year
From what perspective? From Earth, you will never see Jupiter go across the Sun, as the Earth is much closer to the Sun than Jupiter.
When you go higher up it gets colder. Then the lower you go it gets hotter because the closer you are to the inner core the hotter it gets.
depends on the size and how close it is to the sun. the closer to the sun and the smaller the faster. if it is small and far from the sun it will go slower. the closer to the sun the more gravitaional pull.
