The solar system.
The Solar system comprises of the Sun, the eight major planets (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune), several dwalf planets, several moons which orbit planets, many asteroids, some comets, some man-made objects which have been placed in various orbits or sent to explore other objects and interstellar material such as dust and hydrogen atoms.

While none of the objects currently recognized as dwarf planets are as massive as any of the true planets of the solar system, they are still massive objects with substantial gravity, strong enough to keep a moon or several in orbit.
From Latin sol = sun. System means there are several components involved - in this case, the Sun, the planets, etc.
There are millions of them, ranging from the main eight planets, several further dwarf planets, comets, asteroids, kuiper belt objects and meteoroids. All in orbit around our sun.
There are 13 in total: Planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Dwarf planets: Ceres, Pluto, Eris, Makemake, and Haumea. It seems likely that several other large objects, such as Sedna, Qaoar and others, will eventually be recognized as dwarf planets. It also seems likely that more dwarf planets will be discovered.
The solar system consists of the sun, eight planets (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune), their moons, asteroids, comets, and other smaller objects. These celestial bodies are bound together by gravitational forces and orbit around the sun.
Yes we can! And we have! Several planets and moons have water on them!
The modern tools includes several forms of sonar(detection by sound reflection).
The smallest planet in the solar system is Mercury.
That means there are also other planets.
Probably Sirius - but keep in mind, several objects observed as "very bright stars" are actually planets, especially Venus and Jupiter.
