Best Answer

5.2 Earth years
Explanation: Kepler's third law, shown below, relates a planet's orbital period to its orbital radius. T is the planet's orbital period and r is its orbital radius. k is a constant that depends upon the mass of the star at the center of the solar system.so

T2 = kr3

When AU are used in our solar system, k is 1. To solve, cube the orbital radius, so 33 is 27. Then take the square root of the result. The square root of 27 is close to 5.2, so the period of a typical asteroid is close to 5.2 Earth years.

How hot are most asteroids?

The average temperature of the surface of a typical asteroid is -100 degrees F (-73 degrees C).


What kind of gases are in a Asteroid?

A lot of the gases in asteroids are in solid form on the asteroid, because way out in space it's incredibly cold, and the gases actually are in solid form. They would include hydrogen, carbon dioxide, methane, and ammonia.


How are planets asteroids and comets orbits alike?

Rock and/or metallic solids - virtually 100% for a typical asteroid, and a goodly amount (some astronomers think more than half) in a cometary nucleus. They also share in common the fact that they orbit around the sun.


What are facts about asteriods?

The asteroid belt is a region of our solar system between Mars and Jupiter, where a conglomeration of numerous rocky and icy planetesimals have formed a ringlike structure that encircles the sun. One theory is that the gravity of Jupiter was powerful enough to inhibit these rocky bodies from accreting (gathering) into a single planet. As a result, the only body in the belt large enough to qualify as even a minor planet is the dwarf planet Ceres. It's likely that the vast majority of the non-cometary rocky and icy bodies found in the Kuiper Belt, the Scattered Disk, and the Oort Cloud (all of which are found beyond the orbit of Neptune) probably qualify as either asteroids or minor planets. So it's possible to conceive of these structures as being asteroid belts as well, albeit ones that are not nearly so densely packed as the one in the inner solar system. The planetoid belts--the Kuiper and the Main--actually have 2 belts each. Their origin is unknown because no model of planetary formation has been proven. The currently accepted model has no explanation for the twinning of Venus-Earth and Uranus-Neptune and has other serious problems with it. Also, a body that is not a planet can't be called a planet, whether dwarf or minor or otherwise.


What is the composition of asteroid belt?

It depends on the type of meteor. There are three major types of meteors: iron, stony-iron and stony. If it's an iron meteor, it is a hundred percent made up of iron and nickel. Stony-iron meteors comprise of 50 percent iron and 50 percent silicates. Stony meteors are composed of 10 to 15 percent iron and nickel with 85 to 90 percent silicates.

What is typical transition metal?

Typical transition elements are those elements in which d orbital is in the process of completion.d orbital can occupy 10 electrons. if in any element d orbital contain less than 10 electron it means it has incomplete d orbital and d orbital is in the process of completion. for example Sc has electronic configuration 3d1 4s2. it has 1 e in d orbital. so Sc is typical transition elements.

Do asteroids orbit around the whole solar system?

Just like every planet, dwarf planet, comet, and every other member of the solar system, each asteroid orbits the sun in a closed, curved elliptical orbit, with the sun located at one focus of the ellipse. There are no perfectly circular orbits, but if there were one, the sun would be at the center of the circle. Although there are exceptions, the most typical asteroid orbits lie completely between the orbits of Mars and Jupiter. Concerning asteroids in that kind of orbit, you might say that they surround Mercury, Venus, Earth, and Mars, but everything else in the solar system lies outside their orbits.

Does pluo have a stronger gravity than earth?

Assuming you mean Pluto: No, it's gravity is much weaker. Pluto has the size and mass of a large asteroid; quite a bit smaller than a typical planet.
