Asteroids
Asteroids, or planetoids, are rocks larger than meteorites but smaller than planets that orbit around the Sun.

What was the name of the asteroid that hit earth?
They have not been named. There have been many of them over the millions of years.
If you were traveling in deep space, it would be easy to see an asteroid in your path; use your radar to detect it, and then shine a light on it. There would be essentially no natural light, but if you don't have any artificial lights, then you probably don't have a habitat that will enable you to survive in deep space anyway. All spacesuits have lights. So the question would be moot; you would be dead and not able to see anyway.
If you were in a space suit with no lights in deep space, then during the (very brief) interval before you died you would not be able to actually see an asteroid, but you might be able to see the occultation of stars; if a star were to suddenly "disappear", you might reasonably assume that some dark object had come between you and the star.
Answer
There is light in deep space. Just like on earth there is star light, but it would be darker than the darkest night seen on earth. Whether or not an asteroid would be visible depends entirely on what that asteroid is made of and how reflective it is.
What is a rock that falls from outer space?
If it burns up in the atmosphere, it is a meteor. If it manages to make it through the atmosphere and land on Earth, it is a meteorite. A really bright meteor is called a bollide.
Why do the speeds of the comets increase when they get closer to the sun?
It is not just comets- all orbiting bodies speed up as they get closer to the object they are orbiting, as stated by Kepler's Second Law, because the gravity between the two objects gets stronger as they get closer together, as stated by Newton's Law of Universal Gravitation.
What is the general location for an asteroids?
But there are plenty of asteroids that orbit at other distances as well.
What is the difference between a commemorative belt and a replica belt?
A Commemorative belt is the same size as the original but its made of plastic. The Replica Belt is also the same size but its made of metal, so its more authentic.
What is the largest asteroid in the Asteroid Belt?
The largest body in the asteroid belt is Ceres, with a diameter of about 950 km. Although it has long been considered to be an asteroid, Ceres was classified as a "dwarf planet" on August 24, 2006. (The other dwarf planets are Pluto, Makemake, Haumea, and Eris.) The issue of whether Ceres remains an asteroid was not addressed at that time.
What is the asteroid belt evidence of?
Some people (including me) are led to believe that when the planets were being made, there were hundreds. These planets smashed into each other to basically start a planet war. The only ones that were left were our current 9 planets, and the rest settled out to become the asteroid belt.
What is the type of space rock that a company called Planetary Resources is hoping to mine?
Planetary Resources plans to mine asteroids.
Is Venus located inside or outside of the Asteroid Belt?
Venus is located inside the Asteroid Belt. The Asteroid Belt is a region in our solar system between the orbits of Mars and Jupiter where many asteroids are found, while Venus is the second planet from the Sun, closer to the center of the solar system.
Asteroids are practically all in orbits around the Sun, between the orbits of the planets. There is a large main belt between Mars and Jupiter, and more farther out past Neptune.
Spin and wobble of asteroids is caused partly by impacts with other small bodies, and by the gravitational influence of the major planets. Likewise, one of the few things that will stop a spin once it starts would be tidal interaction with planets and moons. This also tends to establish orbital resonance with relatively nearby objects.
Is it true that there has never been a meteorite hit the earth larger than a meter?
No, it is not true. Large meteorites that have hit the Earth are called bolides. There have been confirmed cases of bolides larger than a meter hitting the Earth, such as the Chelyabinsk meteorite in 2013.
Is an asteroid bigger than Saturn?
No. Asteroids are smaller than even the smallest planets. Saturn is the second largest planet in the solar system.
When will human extinction occur?
The human race will not go extinct because of Global Warming. Global Warming is a current threat, but because of the fact many people know about it, people are changing their habits for the better. (Ex; recycling, being aware, reducing their carbon footprints). The human race is not threatened because of Global Warming, but some animal species are as a result of careless actions by humans.
Can an asteroid destroy the earth?
No, an asteroid cannot destroy earth, but a large enough asteroid can have devastating effects on the life on Earth
Asteroids have no effect whatsoever on the health of living things.
(Except in the rare case where one were to fall directly on your head,
or on the planet where you live. THAT kind of event would negatively
affect your health.)
Why are asteroids safe in circular orbits but insafe in elleptical ones?
Asteroids are safer in a circular orbit than an elliptical orbit because being in an elliptical orbit causes them to tumble in an erratic manner. Larger asteroids are sometimes referred to as planetoids.
