What happens to the shape of the orbit of a satellite orbiting the earth if the speed increases?
If the speed at every point of the new orbit is higher than the speed at every point of the old one, then the orbit is smaller, but it can have the same shape. ============================================ Another contributor added: going too fast may give the satellite an elliptical orbit, or may cause the satellite to escape the gravity of Earth if the velocity is too great
How does a satellite stay in one place?
For a satellite to stay in one place over the earth, the satellite must be going in orbit in the same direction that the earth spins. The satellite must also travel at the same pace/speed as the earth spins to give us the 24-hour day that we as people witness. To apparently stay in one place it must be in a synchronous orbit. For the earth this is about 24,000 miles altitude. It must also be an equatorial satellite.
What is the speed of the spaceship?
It varies greatly. It will depend on how far away it is from the object it's orbiting. If it is in a circular orbit around the Earth, its speed can be calculated by the formula: speed = Squareroot(398600/(6371+altitude)) This will give you an answer in kilometers per second.
How many days are in a year why does it happen?
Most years have 365 days, but there are also leap years that have 366 days. The length of the year is designed to give us consistent seasons. The planet Earth travels in its orbit around the sun in a year. Because the length of the year in days is the same as the length of the orbit, we always have winter and other seasons during the same months.
Why orbit of earth is egg shape?
Well, a detailed analysis is probably quite complicated. But to give you a general idea, at a certain speed, the orbit would be circular - the attraction from the Sun is just enough to change the Earth's velocity (i.e., its direction) so that it becomes a circle - maintaining the speed. If the Earth moves slightly slower, then Earth doesn't have enough momentum to keep in a circle, so it would get closer and closer to the Sun, during half an orbit. However, that would also make Earth faster - in fact, fast enough to get away from the Sun again. The final result is a closed orbit, in the shape of an elipse.Well, a detailed analysis is probably quite complicated.

If you were to tie a rope to the Moon and then dangle that rope down to Earth how fast would the end of that rope speed across the surface of the Earth?
In space, or the space between the earth and the moon, there is no "down" so the question asked does not give enough information for an adequate answer. The sidereal period of the moon is 27.321682 days or 655.720368 hours The daily period of the earth is 24 hours. The equatorial circumference of the earth is 6378.1 km So, if you could dangle a rope from the moon down to the earth the end would speed across the face of the earth at speed of the earth's rotation - speed of the moon's orbit. speed of the earth's rotation 6378.1 km/ 24 hours = 265.75 km/hr speed of the moon's orbit 6378.1 km/655.72 hours = 9.7269 km/hr 265.75 - 9.73 = 256.02 km/hr
How miles does earth travel in 365 days?
Briefly:The length of Earth's orbit can be measured in time or space.That is 365.25 days or 940,000,000 kilometers or 584,000,000 miles.See related links from NASA.Explanation:Time: Length of YearThe length of time it takes the Earth to orbit the Sun is365.24219 standard days, where a standard day is defined as 24 hours, not the time it takes the Earth to rotate about is axis.The time it takes the Earth to orbit around the Sun changes by a few minutes each year because the Earth's path is slightly affected by the other planets, mostly Saturn and Jupiter. In 2007 the year was about 11 minutes longer and in 2010 it was 12 minutes shorter, but in 2013, it will be within a minute.Space: Circumference of EllipseTwo ways to calculate the length.1. Use the average speed times the length of a year.For Earth, the orbital period (year) is 365.25 days which takes place at an average of distance of 149,600,000 km from the sun at an average speed of 29.8 km/s.(365.25 days) * 29.8 * (km / s) = 940 416 480 kilometers2. Use geometry.If the Earth's orbit were a circle, the length of the orbit would be the circumference,C=2 pi r.2 * pi * (149 600 000 kilometers) = 939 964 522 kilometersSince the orbit is more nearly an ellipses, we could approximate the circumference as C= pi (a+b), but that does not actually improve the accuracy. The exact calculation of the circumference of an ellipse turns out to be difficult and has been a topic that has occupied the world's best mathematicians. But, for accuracies we need, our answer above is within one percent.
Does the earths rotation cause the sun to remain in orbit?
No. Earth orbits the sun, not the other way around. Earth's orbit depends on the mass of the sun, not Earth's rotation. Earth's rotation does, however, give the appearance that celestial objects revolve around it.
How long does the earth take to orbit arond the sun?
One year, take or give a few minutes. ;-)
Can you give me a sentence using the word orbit?
The minor planet Pluto has an elliptical orbit around the sun.
Why do planes and space shuttles fly at a different speed?
The space shuttle goes into orbit around the earth. In order to stay in an orbit, something that is orbiting has to go at the right speed for that orbit. The orbit the space shuttle goes into has a speed of around 17000 mph. If it went faster, it would go up higher into space away from the earth. If it went slower, it would not have enough energy of motion and it would fall back to earth. The shuttle's big rockets don't just lift it up into space, their main purpose is to give the shuttle this enormous speed so that it can stay in its orbit. A plane engine is not strong enough to make the plane go this fast, but if it did somehow go this fast it would burn up. When it is time to land, small rockets on the shuttle change the orbit so that it goes into the air. The air slows the shuttle down, and it starts to come down faster since it doesn't have enough speed anymore to stay in orbit. The air rushing past the shuttle has friction with the shuttle and gets very hot. As the shuttle goes through the air, it slows down from this friction, until it is finally going slow enough to land. When it lands the shuttle has slowed down to the speed of a plane.
Why is there perigee?
The moons orbit is not a circle its an ellipse. One of the sides of the elliptical orbit is 50,000 miles closer to earth. The moon reaches this spot on its orbit once every 18 years give or take. Hence, at some point in it's orbit, it is the farthest from earth, and at another point is it closest to earth. "Apogee" is when it is at it's furthest point from earth, "perigee" is when it's closest. It went through perigee just the other night.
