Moon, Demos and Phobos
There are 168 known natural satellites (moons) of the 8 major planets. There are also moons around 3 of the 5 dwarf planets (Pluto, Eris, and Haumea). There are more than 200 artificial satellites (or expired satellites) in Earth orbit or scattered throughout the solar system.
Yes. A solar system consists of a sun or star with its satellites. (It can be 2 or 3 stars.) Its satellites are its planets, asteroids, meteors, comets, clouds, and other stuff in orbit around it. A galaxy consists of many solar systems. The Milky Way is a galaxy.
There are twelve (out of 18) planets in the solar system with satellites:Earth [1]Mars [2]Jupiter [66]Saturn [62]Uranus [27]Neptune [13]Orcus [1]Pluto - Charon [3]Haumea [2]Quaoar [1]Eris [1]
well, all planets have different numbers of satellites... if you start from first planet Mercury, it has no natural satellite. Venus is also free of that.. Earth has one big that we can see and its called Moon or Luna(Greek for Moon) but astronomer say that earth has more than one, probably seven or some say two. Mars has two, Jupiter has 63 known satellites to date (including biggest satellite in solar system Ganymede) , Saturn has 60 to 62, Uranus has 27 known satellites, Neptune has 13 known satellites and Pluto has 3 (Not a planet anymore though)
Artificial, Captured and Accreted
3. one orbiting earth, 2 others orbit mars
Its a planet, NOT a solar system.
1) I am learning about the solar system in school. 2) I would love to see the solar system!. 3) Earth is a planet in the solar system. 4) The sun is the biggest star in the solar system.
Natural satellites? none. Uranus - 27 known moons to date Jupiter - 63 known moons to date Saturn - 60 known moons to date Mercury - 0 Mars - 2 Earth - 1 Neptune - 13 known moons to date Pluto - 3 known moons to date Venus - 0 None because Mercury has no moons/satellites at all.
Solar Maximum Mission (SMM): Launched in 1980, SMM studied solar flares and other solar activities. Solar and Heliospheric Observatory (SOHO): Launched in 1995, SOHO studies the Sun's atmosphere, solar wind, and magnetic fields. Solar Dynamics Observatory (SDO): Launched in 2010, SDO observes the Sun in multiple wavelengths to understand solar variability.
Neither Mercury nor Venus have natural satellites. Earth has one natural satellite and several thousand artificial ones. All of the other planets have at least two (Mars) or more.
The four biggest satellites of Jupiter are Ganymede, Callisto, Io, and Europa. Ganymede is the largest moon in the solar system and is even bigger than the planet Mercury. These four moons are known as the Galilean moons, named after Galileo Galilei who discovered them in 1610.
