Our Moon, the planet Mercury, and most of the asteroids and dwarf planets are too small to have an atmosphere.
Earth is the only planet in our solar system known to have large bodies of liquid water on its surface and a protective atmosphere that allows life to thrive.
The difference is semantic; the solar system is the collective identity of all bodies considered together as a whole, i.e., the Sun, planets, etc.; whereas the bodies would refer to each of those making up the solar system: the planet Neptune for example is "a" body in the solar system.
Bodies in the inner Solar System, like Mercury, Venus, Earth, and Mars, are predominantly made of rock and metals. In contrast, bodies in the outer Solar System, like Jupiter, Saturn, Uranus, and Neptune, are primarily composed of gases and ices, such as hydrogen, helium, water, and ammonia. Additionally, outer Solar System bodies are much larger and more massive compared to inner Solar System bodies.
The solar system
But ... there are many bodies in our Solar system that have no atmosphere.
There is no atmosphere for the solar system, space has no air
Our Moon, the planet Mercury, and most of the asteroids and dwarf planets are too small to have an atmosphere.
Earth is the only planet in our solar system known to have large bodies of liquid water on its surface and a protective atmosphere that allows life to thrive.
There are various small bodies in the solar system .These include moon, asteroids, rocks etc.
Mercury has no atmosphere.
Mercury and the Moon do not have significant atmospheres. Mercury's thin exosphere mainly consists of atoms blasted off its surface by the solar wind, while the Moon has virtually no atmosphere, making them both airless bodies in our solar system.

Titan, the largest moon of Saturn, has the most substantial atmosphere in our solar system.
Please be more specific about which solar system.
Bodies in the inner Solar System, like Mercury, Venus, Earth, and Mars, are predominantly made of rock and metals. In contrast, bodies in the outer Solar System, like Jupiter, Saturn, Uranus, and Neptune, are primarily composed of gases and ices, such as hydrogen, helium, water, and ammonia.

Its at the centre of the solar system. All the planets and other bodies are in orbit around it.
