Yes. A lot of the other solar bodies out there have molten cores. All they need is a crack in the crust that makes a defect, and the liquid magma will be forced out of that opening, because of all of the pressure. Sometimes it isn't melted rock that makes the volcano. most of the stellar bodies in the solar system sport geysers that shoot a natural liquid high into the air.

The four bodies in the solar system known to exhibit volcanic activity are Earth, Venus, Jupiter's moon Io, and Saturn's moon Enceladus. Earth has numerous active volcanoes, while Venus has many large volcanoes and evidence of recent volcanic activity. Io is the most volcanically active body in the solar system, with numerous active volcanoes due to intense tidal heating. Enceladus displays cryovolcanism, erupting water vapor and ice from its subsurface ocean.

There are various small bodies in the solar system .These include moon, asteroids, rocks etc.
There are two bodies in the solar system that posses active volcanos. One is Venus, the second planet from the sun. Another is Jupiter's moon Io. Io has almost constantly erupting volcanos, due to the friction caused by Jupiter's immense gravity.
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.
But ... there are many bodies in our Solar system that have no atmosphere.
No, Earth isn't the only body in the Solar System with active volcanoes. Io, the third largest moon of Jupiter has active volcanoes with evidence. Venus, Mars and Pluto are also thought to have volcanoes based on their behaviour.
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. Additionally, outer Solar System bodies are much larger and more massive compared to inner Solar System bodies.
