How do astronomers observe planets that are too far away to see?

Answer 1

Space Telescopes

Planets that are orbiting stars that are far away creating fluctuations in the light that we see coming from the star. Astronomers can observe those planets by measuring the fluctuations of that light.

Answer 2

Several methods exist, but planets around other solar systems are usually found by the gravitational effect they have on their stars. In other words, if the star "wobbles", that is an indication that there is a mass nearby that makes it wobble.

Answer 3

It is rare to detect planets in other solar systems directly. Instead scientists detect them indirectly. As a planet orbits its star it exerts a small gravitational pull on the star. Scientists can then measure the change in the star's spectrum as it is pulled slightly towards and away from earth.

Answer 4

Astronomers use techniques like transit observations and radial velocity measurements to detect planets that are too far away to see directly. Transit observations detect planets by measuring the dip in a star's brightness as a planet passes in front of it, while radial velocity measurements detect planets by measuring the star's wobble caused by the gravitational pull of an orbiting planet.

Answer 5

they studied about them or

they went to the space and no about the planets
