1.土星
Saturn is the sixth planet from the Sun and the second largest planet in the Solar System,after Jupiter.Saturn,along with Jupiter,Uranus and Neptune,is classified as a gas giant.Together,these four planets are sometimes referred to as the Jovian planets,where Jovian is the adjectival form of Jupiter.
2.水星
Mercury is the innermost and smallest planet in the Solar System,orbiting the Sun once every 88 days.The orbit of Mercury has the highest eccentricity of all the Solar System planets,and it has the smallest axial tilt.It completes three rotations about the axis for every two orbits.The perihelion of Mercury's orbit precesses around the Sun at 43 arcseconds per century; a phenomenon that was explained in the 20th century by Albert Einstein's General Theory of Relativity.Mercury is bright when viewed from Earth,ranging from −2.0 to 5.5 in apparent magnitude,but is not easily seen as its greatest angular separation from the Sun is only 28.3°.It can only be viewed in morning or evening twilight.
3.天王星
Uranus is the seventh planet from the Sun and the third-largest and fourth most massive planet in the Solar System.It is named after the ancient Greek deity of the sky (Uranus,Οὐρανός),the father of Kronos (Saturn) and grandfather of Zeus (Jupiter).Though it is visible to the naked eye like the five classical planets,it was never recognized as a planet by ancient observers because of its dimness and slow orbit.[13] Sir William Herschel announced its discovery on March 13,1781,expanding the known boundaries of the solar system for the first time in modern history.This was also the first discovery of a planet made using a telescope.is the seventh planet from the Sun and the third-largest and fourth most massive planet in the Solar System.It is named after the ancient Greek deity of the sky (Uranus,Οὐρανός),the father of Kronos (Saturn) and grandfather of Zeus (Jupiter).Though it is visible to the naked eye like the five classical planets,it was never recognized as a planet by ancient observers because of its dimness and slow orbit.[13] Sir William Herschel announced its discovery on March 13,1781,expanding the known boundaries of the solar system for the first time in modern history.This was also the first discovery of a planet made using a telescope.

Neptune is the eighth planet from the Sun in the Solar System.Named for the Roman god of the sea,it is the fourth-largest planet by diameter and the third-largest by mass.Neptune is 17 times the mass of Earth and is slightly more massive than its near-twin Uranus,which is 15 Earth masses and not as dense.[10] On average,Neptune orbits the Sun at a distance of 30.1 AU,or approximately 30 times the Earth-Sun distance.Its astronomical symbol is ,a stylized version of the god Neptune's trident.
