do all satellites orbit the earth in the same direction?

Yes, all satellites go in the same direction, they just do so at different speeds. What everyone else seems to forget, is that the earth is rotating on its axis. A satellite in a geostationary orbit is going around the earth, matching it's rotation speed.

Earth's rotation is the rotation of planet Earth around its own axis. Earth rotates eastward, in prograde motion. As viewed from the north pole star Polaris, Earth turns counterclockwise.

Velocity, Acceleration and Force Vectors The motion of an orbiting satellite can be described by the same motion characteristics as any object in circular motion. The velocity of the satellite would be directed tangent to the circle at every point along its path.

Under the geocentric model, the Sun, Moon, stars, and planets all orbited Earth. ... The stars appeared to be fixed on a celestial sphere rotating once each day about an axis through the geographic poles of Earth.

They're entirely different. A geostationary satellite sits over one spot on the equator. ... A sun-synchronous satellite is in a low earth orbit designed so that the orbit plane precesses eastward at the same rate the earth orbits the sun (360/365.24 = 0.98565 deg/day).

All orbits are elliptical, which means they are an ellipse, similar to an oval. For the planets, the orbits are almost circular. ... They are highly eccentric or "squashed." They look more like thin ellipses than circles. Satellites that orbit Earth, including the moon, do not always stay the same distance from Earth.

Geostationary satellites don't actually orbit the equator, they are in low inclination orbits that cause the satelite to appear to do a figure 8 in the sky above the Earth. Orbiting near the equator allows the satellite to match the speed of the Earth's spin which is the same at the same latitudes.

As the Earth rotates, it also moves, or revolves, around the Sun. The Earth's path around the Sun is called its orbit. It takes the Earth one year, or 365 1/4 days, to completely orbit the Sun. As the Earth orbits the Sun, the Moon orbits the Earth.

Yes. The Moon, of course, orbits the Earth, which in turn orbits the Sun. The peak of the Full Moon is when the Moon is opposite the Sun – 180 degrees away. Therefore the Full Moon (and the other moon phases) occur at the same time, regardless of where you are located on Earth.

The Earth rotates around a north-south axis as you see on the right. Most maps show North at the top and South at the bottom. To the left is West and to the right is East.

In a similar fashion to Earth's obliquity, the more uniform Earth's orbit is (more like a perfect circle), the less difference there is in climate change throughout the year. Unlike obliquity, eccentricity affects the entire planet approximately the same, instead of primarily changing polar climate.

The orbit will tend to shift over time but it will stay orbiting the Earth in the same way that the Moon still orbits the Earth after millions of years. But usually we don't want them to stay in a particular orbit forever. A satellite has a useful lifetime of between 5 and 15 years depending on the satellite.

The GPS satellites are not in a geostationary orbit, but rise and set two times per day. ... By combining signals transmitted by several satellites and received simultaneously, a GPS receiver can calculate its position on the Earth (i.e., its latitude and longitude) with an accuracy of approximately 10 m.

The sun, earth, and moon are held together by gravity, and they interact in lots of ways. The moon orbits the earth because of the pull of the earth. And the earth orbits the sun because of the pull of the sun. Because of the way they move relative to each other, we see phases and eclipses.

So, How Do Satellites Stay in Orbit? Satellites are able to orbit around the planet because they are locked into speeds that are fast enough to defeat the downward pull of gravity. ... Once the rocket reaches its determined location it drops the satellite into its orbit.

So, How Do Satellites Stay in Orbit? Satellites are able to orbit around the planet because they are locked into speeds that are fast enough to defeat the downward pull of gravity. ... Satellites do carry their own fuel supply, but unlike how a car uses gas, it is not needed to maintain speed for orbit.

While polar orbits have an inclination of about 90 degrees to the equator, geostationary orbits match the rotation of the Earth. ... Out of the three types of orbits (low, medium and high Earth orbits), polar orbits often fall into low Earth orbits.
