How fast an asteroid travels depends on its distance from the sun. The average orbital speed is 25 kilometers per second. The closest orbiting asteroid to the sun travels at 30 kilometers per second.

Wiki User
∙ 13y agoGenerally an asteroids brightness will change if a) a larger surface area is presented to the Sun or b) it is closer to the Earth
Wiki User

How are all of the planets kept in orbit around the sun?
all the planets stay in orbit around the sun because of the sun's gravitational pull. The high orbital speed that keeps the planets from falling all the way into the sun and since there is no friction in the vacuum of space , that speed dosen't slow down.
Does the sun travel around the planets or do the planets travel around the sun?
The planets travel around the sun.
How does a planets distance from the sun affect the planets orbit speed?
the closer you are to the sun it affects the planets speed cause of the suns gravitational pull
How are planets kept in their orbits as they revolve around the sun?
All the planets stay in orbit around the sun because of the sun's gravitational pull. Now you are probably wondering why the planets don't all get sucked into the sun,well it is the high orbital speed that keeps the planets from falling all the way into the Sun and since there is no friction in the vacuum of space, that speed doesn't slow down.
How Do Planets Travel Around The Sun?
the planets go around in circles around the sun
Why do the 4 inner planets revolve around the sun at a faster speed?
Their closer to the sun.
Which of the following planets revolves around the sun with the greatest speed?
earth
Do all the planets travel around the sun at the same speed yes or no?
no they do not

Do planets revolve around the sun at the same speed?
A planet has an elliptical shaped orbit. It orbits with a constant angular speed, but a varying linear speed.
Why sun is constant at its position where as planets and satelitites change their position?
The sun is not really fixed, it's moving in our galaxy at high speed, in orbit around the galactic core. All of the planets are going with the sun, locked into it's huge gravitational pull.
Does the sun travel around the planets or do the planets travel around the sun?
The planets travel around the sun.
Why does a planets distance from the sun change?
To be in a perfect orbit around the Sun, maintaining always the same distance, at a specific distance a planet would need a very specific speed. Since it is unlikely that it just happens to have the correct speed, it will move around the Sun in an ellipse instead.
How does a planets distance from the sun affect the planets orbit speed?
the closer you are to the sun it affects the planets speed cause of the suns gravitational pull
Does the sun travel around the sun or do planets travel around the sun?
The planets orbit (travel) around the Sun.
How does gravity keep planets orbiting the sun?
Gravity attracts masses together, especially large masses. So all planets are attracted towards the Sun. The Sun is attracted likewise towards the planets, but as the Sun has a much larger mass than any of the planets, the Sun is moved extremely little by the gravity of the planets.The planets also have a large speed perpendicular to the direction to the Sun. This is their orbit speed. If they did not have that perpendicular speed, they would quickly be drawn directly towards the Sun and be absorbed completely by the Sun. But because of the combination of the perpendicular speed and the gravitational pull from the Sun, the planets are kept in their orbits.And because the planets move in almost a perfect vacuum, there is nothing to slow down that speed. So the orbits are as good as permanent.It is, by the way, exactly the same situation that keeps the Moon rotating around the Earth, or any other moon rotating around its planet.The orbital speed of the Earth around the Sun is about 29.8 km/s in average. So, we all move at the amazing speed of 30 kilometers per second around the Sun! That is around 107,000 km/h or 66,700 mph. We completely owe our life to that speed. If Earth stopped, the Sun would quickly absorb us. :o)
