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

Why is earth inhabitable and other planets are not?
Earth is habitable because it has the right conditions to support life, such as a suitable atmosphere, liquid water, and a stable climate. Other planets may not be habitable due to extreme temperatures, lack of atmosphere, or high levels of radiation that make it difficult for life as we know it to survive.
What planet has a atmosphere with gases used by living things?
Earth is the only planet known to have an atmosphere rich in gases like oxygen and nitrogen, which are essential for supporting life as we know it. Other planets in our solar system have atmospheres with different compositions that would not support life as we know it.
Does space have an atmosphere or is it only planets that have them?
Space does not have an atmosphere. It is generally considered a vacuum. Planets and some moons have atmospheres.
Which planet has a large percentage of oxygen in its atmosphere?
Earth has the largest percentage of oxygen in its atmosphere compared to other planets in our solar system. Oxygen makes up about 21% of Earth's atmosphere, which is essential for supporting life as we know it.
How do the inner and outer planets atmosphere different?
the outer planets are gaseous and the inner planets are not
Is atmosphere same in other planets?
No
What is the atmosphere of other planets made up of?
cells
Is earth's atmosphere stronger than all the other planets' atmosphere?
A planet's atmosphere doesn't have strength.
How is the atmosphere of Venus different from that of other terrestrial planets?
yes
What planet has many craters but no atmosphere?
There are probably a very great number of planets in our galaxy with no atmosphere. Of the 400+ planets that we know of, we can only determine the presence or absence of an atmosphere for the 8 planets in THIS solar system; our technology is not yet good enough to study atmospheres from several light-years distance. Of the planets of this solar system, we are fairly sure that Mercury has no atmosphere to speak of. Of the other seven, we know that Mars has a very thin atmosphere, but enough to use a parachute in. If we include dwarf planets, we can say with some certainty that Ceres doesn't have enough mass to retain an atmosphere, and Pluto's atmosphere is almost certainly all frozen by now.

What does earth's atmosphere have that other planets don't?
Earth's atmosphere has a unique composition compared to other planets. It contains a significant amount of oxygen, which supports the existence of complex life forms. Additionally, Earth's atmosphere has an ozone layer, which protects the planet from harmful ultraviolet radiation. Lastly, Earth's atmosphere is denser than most other planets, allowing for the regulation of temperature and the retention of water on its surface.
Why do meteoroids hit Mercury but not other planets?
Meteoroids are small enough that they will usually disintegrate when they enter a planet's atmosphere. Mercury has no atmosphere to speak of, and so it is not shielded in this way. Larger asteroids still do strike other planets.
Do planets have Ozone?
Earth has an ozone layer in atmosphere. It is present in the stratospheric region. Other planets which have oxygen in their environment might have ozone.Some planets like earth do. Others might have.
Which of the planet other than earth has an atmosphere and season?
Mars has an atmosphere, although it is much thinner than Earth's, and experiences seasons similar to Earth due to its axial tilt. This results in temperature variations and changes in weather patterns on the planet.
Do any other planets have an atmosphere like earths and if they did could it support life?
Some other planets, such as Venus and Mars, have atmospheres, but they are very different from Earth's. Venus has a thick atmosphere with extreme heat and pressure, while Mars has a thin atmosphere primarily composed of carbon dioxide. Both planets are unlikely to support life as we know it due to their harsh conditions.
Do all planets have wind?
Not all planets have wind. Wind is caused by the movement of gases in an atmosphere, so planets without a significant atmosphere, like Mercury or the Moon, would not have wind. Additionally, the intensity and frequency of wind can vary greatly depending on factors such as atmospheric composition, temperature gradients, and surface features.
