Why do satellites first revolve around the earth and then reach another planet?

Answer 1

Exactly the same way. Both the Moon and Mars have gravity and Newtons' laws of motion apply everywhere. -----

Most communications satellites are in a stationary orbit, in that they move about very little, and rotate at the same speed as the earth. That's what makes satellite TV possible, among other services.

That's not to say that as they revolve around another planet (as some do here on earth) that they have to be located at the planet's equator. They can revolve around a planet in any direction as long as the centfifugal force and the planet's gravity are in balance in regards to the weight of the satellite.

Here on earth, our communications satellites move in a large, lazy figure-eight pattern, losing some altitude due to some atmospheric drag which in turn causes them to speed up and the centrifugal force causes them to gain altitude as they try to fly farther away, where drag causes them to slow again.

Satellites usually stay within a defined area, normally referred to as `the box`, and under ideal conditions, when trying to set up a satellite receiving or transmission dish, it's always preferable to do your alignment when the satellite is `in the center of the box`. That way, as it works its way back and forth, the signal degradation is about the same on the leading and lagging edges of the box. It's also predictable enough to be able to determine the day and time the satellite will be in the center of the box, which usually lasts only a couple of hours at the most.

because satelites revolve or atract to something of a mayor force ..this is because of the gravitorial force it has over it .. a satelite has to posses a much minor mass than the object it orbits so it doesn't significantly affect the other's trayectory... In a contrary case it is considered a binary system.

----If the planets act as sattelites to the sun(sun is mayor force)-----then satelites like the moon act as the planet's satelites(planet is mayor force )

Ex: Mayor force-Earth

minor force to Earth-moon

VISUAL CONCLUSION:

--SUN (biggest gravitorial mass we little people know about)

-- EARTH(satelite to Sun-has less gravitorial force)

--MOON( even less gravitorial force= satelitle to Earth)---

Answer 3

Any orbit is a delicate balance between gravity and inertia; inertia that keeps the satellite moving straight forward out into space, and gravity from the primary trying to pull the satellite in.

Answer 4

Most satellites stay in orbit round the Earth but a few go to other planets.

Actually, if they leave Earth orbit they are called space probes, not satellites.

While travelling through the solar system they spend most of the time in free-fall in orbit round the Sun.

The onboard engines are used only to establish the spacecraft into the right orbit to reach its chosen destination. That is the only way to conserve enough fuel to travel to other planets.

Space probes use the gravity of the planets (and the Sun) to help them reach their targets most efficiently. This is called a "gravity assist" or a "slingshot effect".

The path that a space probe takes is sometimes quite complicated and not at all the trajectory you might expect.

Answer 6

The orbital and rotational periods of the moon are the same.

The moon always shows the same side to Earth (well it does swing back and forth a little as seen from here).

Answer 7

a satellite is held in orbit around any planet by the affect of that planets gravitational well. A large body in space warps the gravitational field much like a Bowling ball on a taut sheet.

Answer 8

The moon is the only natural satillite orbiting the earth.
