Just small rocks (called metheorites), remainders of bigger rocks, comets, planets, stars and/or any other objects travelling across universe.

Why does a space shuttle need to travel so fast when entering earths atmosphere?
Although it reaches incredible speeds, a Space Shuttle is not going fast when it enters the atmosphere. The gravitational pull of Earth, or just gravity, are pulling down on the space shuttle with immense force.
What type of pattern does the earths orbit take around the sun?
speeds up
Is it possible to accidentally leave the atmosphere?
It is only possible to escape the Earth's gravity by moving away from it at approximately seven miles per second. Seeing as it is very difficult to move at such high speeds by accident, it would not be possible to accidentally leave the atmosphere.
Dying comet fragments that battered Jupiter travel at speeds?
meters and kilometers
Pieces of rock that strike the surface of a moon or planet?
These are meteoroids, small pieces of rock debris in space. They enter the earths atmosphere at high speeds, burning up brightly as shooting stars for a brief period due to the friction against the gas in the atmosphere - at this point they are referred to as meteors. If any surviving pieces are found on the surface, they are called meteorites. Since the moon has no atmosphere, meteoroids are able to survive the decent more easily, since there is no gas to cause them to burn up through friction.
What are the small pieces of rock that enter earths atmosphere at speeds of 15 to 70 k's and burn up called?
meteors!:)
Where would a satellite revolving around earth land if it crashed?
It will most likely burn up through the earths atmosphere on re-entry. The satellites travel at very high speeds, and are not designed to withstand the brunt of the earths atmosphere at the speeds at which they orbit the earth. You might get some bits left over, but these should be quite small. Operators try to land the satellite in the sea once it has reached the end of its life.
What is the sandard unit for velocity?
The SI unit is meters/second. Also in common use is kilometers/hour, or (for high speeds, such as those that occur in astronomy) kilometers per second. In the United States, miles/hour is used instead.
What are the average wind speeds on mercury?
There are no wind speeds to discuss on Mercury, since there is no atmosphere there.

What rate does the moon travel at?
it travels at many different speeds depending on the position of its orbit at the time, it has been recorded going about 1 kilometer per second and 1.91 kilometers per second.
Do jet streams blow at speeds of 200 to 400 kilometers per hour?
Jet streams blow at speeds of 200 to 400 kilometers per hour.
Wind speeds on mercury?
There is no wind because Mercury has no significant atmosphere.
What type of pattern does the earths orbit take around the sun?
speeds up
Is there evidence of wind on the planet of Jupiter?
There is evidence of wind on the planet Jupiter. Winds can reach speeds of 100 meters per second, or 360 kilometers per hour.
Why is it the opposite converting seconds to hours and converting meters per second to kilometers per hour?
Because in the case of the speeds, the measures of time are in the denominator (as indicated by "PER").
