The speed you need to go depends on the orbit you are trying to achieve. For low-Earth orbits (LEO) the satellite must be going about 18,000 miles per hour, but the higher the orbit, the slower you need to go.
It depends on the rocket's orbital height.
The formula is: Velocity = square root of ( G times M divided by R )
G is 6.67 x 10-11 N m2/kg2
M is the planet's mass (Earth's is 5.9736 x 1024 kg)
R is the distance between the rocket and the center of the planet (add the orbital height to the planet's radius at that point)
Make sure you use meters for the rocket's height.
For example, the international space station's orbital height is about 380 kilometers, and Earth's radius averages at about 6365 km, so we'll use 6,745,000 meters
square root of ( (6.67 x 10-11 N m2/kg2 ) x (5.9736 x 1024) / (6.745 x 106) = square root of (59,071,775) = 7686 meters per second = 7.7 km/s

Anywhere at all outside Earth's atmosphere. In its orbital area or very close to the atmosphere
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune
The use of a telescope from orbit is going to be more clear. It is not very easy to do so, though. The orbit eliminates atmospheric interference. However, you have to get the telescope into orbit in order to use it. And connect to it from your remote location.
Would you believe 'none'? Freedom 7 performed a sub-orbital flight, meaning it wasn't going fast enough to achieve orbit. The flight went as high as 116 miles up and landed 300 miles downrange of the launch site. In order to achieve orbit, a spacecraft has to get to about 18000 miles per hour or 8 kilometers per second. This was not achievable with the Redstone rocket Alan Shepard flew.
Earth has an average eccentricity in its orbit of 0.0167. This compares with 0.0068 for Venus and 0.205 for Mercury, which are the minimum and maximum eccentricities in the eight planets. So, the Earth's orbit is not too far from circular. In order of increasing eccentricity, the list of planets is: Venus Neptune Earth Uranus Jupiter Saturn Mars Mercury.

This all depends on orbital altitude. In order to maintain orbit around the Earth a rocket needs to be traveling at least 12 km/s.
Mars and Venus orbit closest to the earth in the order sunward to rimward: Venus, Earth, Mars.
the sun has like a magnetic field and the earth has to orbit it. in order to do so it spins on its axis
to stay
Like any other satellite, including the Moon, it stays up by centripetal force. Like a weight being whirled around your head on a string it would fly off in straight line if the force holding it in were to disappear. With the weight, this force is the tug of the string. With the space station it's gravity. The speed of the space station is just sufficient to keep it from falling to Earth, but also not so great that it would fly off into space. If the speed of the space station were to drop, it would fall to Earth.
The 'orbit' is the term we use to refer to the path that a body follows under the influence of its gravitational interaction with another body. The earth moves in its 'orbit' around the sun, always staying roughly 93 million miles distant from the sun. The earth makes one complete trip in its orbit around the sun in 1 year. In order to do that, the earth's speed in its orbit around the sun is almost 67,000 miles per hour ! At the same time, from the vantage point of an observer on the earth, the moon moves in its 'orbit' around the earth, always staying roughly 1/4 of a million miles from the earth. The moon makes one complete trip in its orbit around the earth in a little less than 1 month. In order to do that, the moon's speed in its orbit around the earth is about 2,300 miles per hour.
No. If they did, air resistance would quickly slow them down and they would fall out of orbit. In order to be in a stable orbit, the satellites must be out of the atmosphere completely.
Natural satellites are organic objects that orbit the earth such as the moon. Artificial satellites are objects humans propel through the earth's atmosphere in order to orbit the earth such as satellites for TV and radio signals.
The rocket will have to accelerate in order to escape the bonds of Earth's gravitational pull.Accelerate now!
In order for the moon to have been captured by the earth, it has to be smaller than the earth. If it were bigger, it would have pulled the earth into its orbit, making the earth the moon.
Earth takes a lot longer to make one complete order around the sun than Mercury does. The time required for Mercury to make one orbit is equal to 88 Earth days (whereas one orbit for Earth is about 365 Earth days).
