hi koleSPACE
The Earth's atmosphere gets thinner and thinner as we go away from the earth. It becomes negligible at a point in space. Beyond that, there is no atmosphere, only vaccum.
The Exosphere. Beyond it is outer space.
The atmosphere is the layer of gases surrounding Earth that is held in place by gravity and provides the air we breathe. Space, on the other hand, is the vast expanse beyond Earth's atmosphere where there is a near-vacuum environment and little to no air. It is where celestial bodies like stars and planets exist.
That study is known as "astronomy."

Atmosphere is the space surrounding any planetry body where the body exerts its gravitational pull. Space is anything / everything beyond the atmosphere
The moon is far beyond the earth's atmosphere. The boundary between the atmosphere and outer space is generally considered to be an altitude of 62 miles, although there is a noticeable effect on spacecraft as high as 75 miles. The average distance from the earth to the moon is 233,000 miles.

The last layer of the Earth's atmosphere is the exosphere. This layer is the outermost layer of the atmosphere and extends beyond the thermosphere. The exosphere is where the atmosphere gradually transitions into outer space.
Objects beyond Earth's atmosphere include satellites, space stations, spacecraft, and celestial bodies such as planets, stars, and galaxies. These objects play important roles in scientific research, communication, navigation, and exploration of space.
NASA (National Aeronautics and Space Administration) is the organization that conducts research into problems of flight within and beyond Earth's atmosphere.
