What is the linear speed of mercury in its orbit about the sun?

The linear speed of Mercury in its orbit around the Sun varies, but on average, it is about 48 km/s. Mercury's speed is fastest when it is closest to the Sun (perihelion) and slowest when it is farthest from the Sun (aphelion) due to Kepler's laws of planetary motion.


How long does the revolution take to go around the sun?

It takes 365 solar days for the Earth to make a revolution around the sun. The distance of the Earth from the sun along with it's access are what cause the change in seasons. The speed of the orbit is he speed is 108,000 km/h.


How many earth days does it take for Pluto to orbit the sun?

It Take's Pluto 243 Earth Day's, To Orbit The Sun? Pluto is farther away from the sun than Earth, therefore, since it has a longer way to go to completely orbit the Sun, there is no way it can take only 243 days


What do planets do when they orbit the earth?

There are no planets orbiting the Earth because all eight of them orbit the Sun. But the Moon orbits the Earth, and all it does is go round and round in a rather complicated orbit which is disturbed by the Sun's gravity.


How fast of speed does a astriod go?

I assume you mean "asteroid". The speed of an asteroid is comparable to that of a planet. For example, an asteroid with an orbit similar to Earth's orbit would have a speed similar to Earth, which moves around the Sun at a rate of 30 km/second. An asteroid that is much further out will be slower; one that gets closer to the Sun will move faster, at least during part of its orbit.You can calculate the speed of an asteroid from Earth's speed, and the relative distances to the Sun, using Kepler's Third Law.

How long would be a second if the Earth would turn at a different speed?

a second will become less because it takes 365 days for the earth to orbit the sun and if the earth becomes faster it will take less day to orbit the sun, so if that happens time must go faster to keep up with the speed and time our earth takes to orbit the sun.


What are some examples of real life hyperbola?

The orbit of objects that approach the Sun, or Earth, from far away, above a certain critical speed.At a certain critical speed, the orbit will be a parabola. Above the critical speed, the orbit will be a hyperbola. (In both cases, the object will go away, never to come back.) Below the critical speed, the orbit is an elipse or a circle.The orbit of objects that approach the Sun, or Earth, from far away, above a certain critical speed.At a certain critical speed, the orbit will be a parabola.

Why is mars not visible when in between the sun and the earth?

the orbit of mars is outside that of the earth's orbit so it can't go between earth and the sun


Why does it take a year for the earth to go right round the sun?

because of the fact that the earth only goes a certain speed among its orbit and it is a certain distance to travel around the sun


What do you call it when the earth go around the sun?

Is the earths orbit or the sun bigger?

If the Sun were larger than Earth's orbit, we'd be inside it. Are we inside it? There you go.
