There are many natural satellites in the solar system, and some new satellites are discovered every year. The moon is the only natural satellite of our earth, so where does the moon rank among the satellites in the solar system? So let’s use constellation knowledge to reveal the ranking of the size of satellites in the solar system? Let’s see where the moon ranks!
The top 10 satellites in the solar system are ranked among the top 10 satellites in the solar system. The four satellites, also known as Oberon (English: Oberon), are the largest satellites farthest from Uranus.
TOP9 Rhea Rhea, also known as "Rhea", is the second largest satellite orbiting Saturn and the ninth largest satellite in the solar system. Rhea is made of ice, with a density of about 1.233 g/cubic centimeter. This low density indicates that it is composed of 25% rock (density 3.250 g/cm3) and 75% water ice (density 1.000 g/cm3).
TOP8 Titania (Titania) is the largest satellite of Uranus and the eighth largest satellite in the solar system. The surface is also covered with volcanic ash. This indicates that volcanic activity occurred. There are grand canyons thousands of kilometers long, probably formed when the water inside froze, expanded, and cracked the weak outer shell. Its surface has also been re-covered with a dark substance, possibly methane or water ice.
TOP7 Triton Triton is the largest satellite orbiting Neptune. It is also one of the coldest objects in the solar system. It has a complex geological history and a relatively young planet. surface.
TOP6 Europa Europa, also known as "Europa", is one of the natural satellites of Jupiter. Among the 67 known satellites of Jupiter, Europa is the fourth largest in diameter and mass and the sixth closest to Jupiter in orbit. Slightly smaller than the Moon, Europa is composed primarily of silicate rock and has a water-ice crust and possibly an iron-nickel core. It has a thin atmosphere, consisting mainly of oxygen. Its surface has numerous cracks and streaks, and craters are relatively rare. It has the smoothest surface of any known solid object in the solar system.
TOP5 Moon The moon is the natural satellite we are most familiar with. Its diameter reaches 3476 kilometers, which is equivalent to a quarter of the mother planet Earth. However, even though it is so huge, it only ranks fifth in size. . However, in recent years, with the development of human science and technology, people have discovered that the moon, a satellite, is becoming more and more mysterious. Because in the entire solar system, its ratio to its parent star, the Earth, is incredible. You must know that even other satellites that are slightly larger than the moon, such as Ganymede, Titan, etc., are pitifully small compared to their parent stars. The diameter of the moon reaches 1/4 of the earth. Such a close ratio is unique in the solar system. Therefore, some people even suspect that the moon is the work of aliens.
TOP4 Io Io, also known as "Io", is the closest satellite to Jupiter among the four Galilean satellites of Jupiter. It has a diameter of 3,642 kilometers and is the fourth largest in the solar system. Satellite, Io is slightly larger than Earth's satellite, the Moon.
TOP3 Callisto Callisto, also known as "Callisto", was first discovered by Galileo Galilei in 1610. Callisto is the third largest satellite in the solar system and the second largest satellite of Jupiter, after Ganymede. Callisto's diameter is 99% that of Mercury, but its mass is only one-third. The satellite's orbit is the farthest from Jupiter among the four Galilean satellites, about 1.88 million kilometers.
TOP2 Titan Titan, also known as "Titan", is a satellite orbiting Saturn. It is the largest of Saturn's satellites and the second largest satellite in the solar system. Discovered by Dutch physicist, astronomer and mathematician Christian Huygens on March 25, 1655, it was also the first satellite discovered in the solar system after the Galilean satellites of Jupiter. Because it is the only satellite in the solar system with a thick atmosphere, it is highly suspected of having life forms. Scientists also speculate that methane in the atmosphere may be the basis of life forms. Titan can be regarded as a time machine, helping us understand the earliest conditions of the earth and uncover the mystery of how life on earth was born.
TOP1 Ganymede Ganymede, also known as "Ganymede", is a satellite orbiting Jupiter with an orbital period of about 7 days. In order of distance from Jupiter, Ganymede ranks seventh among all the satellites of Jupiter and third among the Galilean satellites. It maintains an orbital vibration relationship of 1:2:4 with Europa and Io. Ganymede is the largest moon in the solar system, with a diameter larger than Mercury and about half the mass of Mercury.
