How do you know what is in the atmosphere of other planets?

Answer 1

When white light falls on and is then reflected off the surface or atmosphere of a planet, the elements and compounds on the surface and in the atmosphere of the planet modify the reflected light (e.g. they may absorb some of it).

Thus if you spread out the light reflected by the planet using a spectrometer attached to a telescope, you can see how the light has been modified and by analyzing the pattern of the modifications observed infer the elements and compounds on the planet or in its atmosphere that caused this.

This tells you what is in that planets atmosphere.

Answer 2

Because we can see them.

My cousin has a telescope and we set it up in the back yard and looked at the planets ourselves..Just buy a telescope or ask around to find out if any of your friends have one and you can see the planets for yourself. They are really there.

Answer 3

Scientists use a variety of tools and techniques to study the atmospheres of other planets, such as telescopes, spacecraft, and spectroscopy. By analyzing the light that passes through or is emitted by a planet's atmosphere, researchers can determine the presence of different gases and particles. Additionally, data from missions like the Mars rover or spacecraft like Cassini help provide valuable information about the composition of other planets' atmospheres.

Answer 4

f there fully developed with a rocky core.

Answer 5

Stars that wobble are presumed to have a large planet or planets tugging on them. Stars that dim with a certain period probably have a (dark) planet passing between them and the observer.

Answer 6

if we had an extremely fast rocket with plenty of food and incredible scientists

Answer 7

They can be seen with a telescope.
