It's the gravitational effect of the Sun combined with the inertia of the planets.
Their inertia (Newton's first law of motion) would make the planets move in straight lines, but the gravitational force makes them follow elliptical paths and they orbit the Sun.
The object is moving forward at high speed and tends to travel in a straight line. But the gravitational pull of the Sun causes it to accelerate towards the Sun. The combined effect is that the object's path bends sideways, continuously.
The centripetal force exerted on the telescope by gravity is balanced with the centrifugal force of the object exerted on e.g. earth.

What keeps earth in its orbit?
The sun's gravitational pull keeps the earth in orbit around it.
What are spying satellites?
satellites that spy typically in a low earth orbit with a big telescope looking down at the ground, like google satellite on steroids
Explain what keeps the moon orbiting Earth?
Because the moon moves with a certain speed in its orbit, that orbital motion produces a centrifugal force which opposes the attraction of gravity. The balance between gravity and centrifugal force keeps the moon in orbit. The moon continues to orbit at the speed it does, because of its inertia. Moving in the vacuum of space, the moon does not encounter resistance to its motion. There is, however, some energy lost as a result of tidal forces, and that will, over a very long period of time, eventually alter the moon's orbit.
After a shuttle is launched into orbit what happens to gravity?
There is no gravity in space but the shuttle stays in orbit because of the Earths gravity and inertia. The inertia keeps it going in a circular motion. In space the Earth's gravity is strong enough to hold something in orbit but not strong enough to pull it to Earth's surface.
An instrument that makes small distant objects visible?
telescope or maybe binoculars
What is the telescope that is in orbit around the earth?
The telescope in orbit around the earth as of 2010 is the Hubble Telescope.
Where is the telescope?
In orbit around Earth.
What keeps the earth in orbit with the sun?
Gravity and Inertia keeps the earth in orbit
Is it easier to examine Neptune with a telescope from Earth or with an orbiter?
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.
What is the largest telescope to be put into orbit?
The largest telescope put into orbit is the James Webb Space Telescope (JWST). Scheduled to launch in late 2021, the JWST will have a mirror diameter of 6.5 meters, significantly larger than the Hubble Space Telescope.
What is the force that keeps planet in orbit?
the suns gravity keeps the planets in orbit
Did NASA put a telescope in orbit on Jupiter?
No.
Where is the Chandra telescope?
In orbit around Earth.
When was the hubble telescope built?
The Hubble Telescope was launched into orbit on April 24, 1990.
When was the first space telescope built by NASA place into orbit?
The Hubble telescope was the first telescope built by NASA and placed into orbit. The original launch for the telescope was delayed because of the disaster seen by the Challenger.
Definition of hubble telescope?
The space telescope that was carried into Earth orbit by a space shuttle in 1990.
What is the largest telescope ever been put in to orbit?
the largest telescope ever been put into the orbits is the Hubble space telescope
