What is the most expansive layer of the Earth?
The Earth's mantle comprises the bulk of the Earth.
On what layer of the earth do erosion and weathering occur?
the crust- most outer layer of earth
Which layer of the earth weighs the most?
ozone layer or the trophosphere
What is the uppermost layer of the earth?
The exosphere is the upper most layer of earths atmosphere. The lithosphere or crust is the outermost layer of the solid Earth.
The outmost layer of the earth?
The outer most layer of the Earth is the Crust. That is if you are talking about the ground. If it is the atmosphere then it is the Exosphere
Which factor would most likely cause communications satellite orbiting earth to return to earth from its orbit?
That will happen if the satellite loses energy. This is usually caused by air resistance, if the satellite's orbit is too low.
The point Earth is farthest away from the Moon in its orbit is called what?
The point in the orbit of the moon or of an artificial satellite that is most distant from the center of the earth is called the 'apogee'.
What are the most common space crafts that orbit the earth?
Aspacecraft/Satellite
What is the name of the satellite visible over Skegness UK at about 21.00 on 2 Sept 2010 travelling approx west to east?
Are you sure it was a satellite ? The International Space Station is also visible from earth. Most satellites are in a geo-stationary orbit - in that they orbit the earth at the same speed the earth spins on its axis.
What are the main differences between geostationary orbit and polar orbit?
A polar orbit is an Orbit in which a Satellite passes above or nearly above both of the Geographical poles of the body (usually a planet such as the Earth, but possibly another body such as the Sun being orbited on each revolution. It therefore has an Inclination of (or very close to) 90 degrees to the Equator. Except in the special case of a polar Geosynchronous orbit, a satellite in a polar orbit will pass over the equator at a different Longitude on each of its orbits.A geostationary orbit (GEO) is a circular orbit directly above the Earth's Equator From the ground, a geostationary object appears motionless in the sky and is therefore the Orbit of most interest to operators of Communication Satellites. Their orbital periods (time taken to revolve around earth) is exactly the same as the planet's (such as Earth's) rotational period. The Geosynchronous orbit is approximately 36,000 km above Earth's surface.geostionary satellites are positioned at an exact height above the earth, at this height they orbit the earth at the same speed at which the earth rotates on its axis whereas polar satellites have a much lower orbit, orbiting the earth quite quickly, scanning different areas of the earth at fairly infrequent periods.
What is the satellite that always stays over one spot on Earth?
A "geo-synchronous" orbit is one in which a satellite orbits in exactly 23 hours 56 minutes, the same rate at which the Earth spins. So while the satellite is moving and the Earth is moving, they are moving together at the same angular speed. This only works for equatorial orbits.
What is the difference between moon and satellite?
The word Moon is a name given to the natural satellite in orbit around the Earth. We attribute this name to most objects large enough to see in orbit around other planets. In this way Moons and Natural Satellites are one in the same. Artifical Satellites are what we put into orbit around the earth IE GPS Satellites, but are man made.
What do you call the point in a satellite's orbit farthest from its planet?
In general the farthest point in a satellite's orbit from its focus is its apoapsis. If the focus is the Sun or Earth however then you would say the satellite's farthest point is its aphelion and apogee, respectively.
Could a planet be a satellite?
By definition a planet cannot be a satellite. A planet is a body that has cleared most of the debris in its orbit about a star. However, a satellite might have an atmosphere. Titan, the largest moon of Saturn, has an atmosphere more dense than that of earth.
The planet with the most satellites?
Earth. Earth has one natural satellite, the moon, which is in orbit around the earth. There are around 3000 man made satellites currently in orbit. Jupiter has the most natural satellites (moons), over 60 have been confirmed. It has no man made satellites in orbit around it, but did have one between 1995 and 2003, an orbiter called Galileo.
Which layer of the atmosphere do communications satellites orbit?
Most communications satellites operate outside of the earth's atmosphere. The GPS satellites are about 23,000 miles from the surface of the earth.
How long does it take for a satellite to orbit the earth once?
There are a great number of satellites around the Earth, each in its own orbit. The time to complete each orbit varies from about 90 minutes, for satellites in LEO (low Earth orbit) to 24 hours for satellites in geo-synchronous orbits. There are some satellites in higher orbits that take even longer. One the satellites in LEO is the International Space Station, and the Shuttles when in orbit. All of the GPS satellites are in highly-inclined 12-hour orbits. Most communications satellites are in geosynch 24-hour orbits, so that the satellites appear to remain stationary in the sky as they orbit the Earth. You can display a real-time 3-D plot of most satellites now in orbit by running NASA's "J-Track 3D" program at http://science.nasa.gov/Realtime/jtrack/3d/JTrack3d.html.
