近日点

The Earth reaches its perihelion in early January, when it is closest to the Sun.
地球在1月初达到近日点，此时它离太阳最近。
At perihelion, the distance between the Earth and the Sun is about 91.4 million miles.
在近日点，地球与太阳之间的距离约为9140万英里。
The orbit of Mercury around the Sun has a high eccentricity, resulting in a large variation in distance from the Sun at perihelion and aphelion.
水星绕太阳的轨道具有很高的偏心率，导致在近日点和远日点时与太阳的距离有很大变化。
Venus reaches its perihelion about every 584 days, when it is about 66.7 million miles away from the Sun.
金星每约584天达到一次近日点，此时它距离太阳约6670万公里。
The perihelion of Mars occurs about every 2 years and 1 month, when the red planet is about 128 million miles away from the Sun.
火星的近日点大约每2年零1个月发生一次，此时红色星球距离太阳约1.28亿英里。
The orbit of Pluto is highly elliptical, with a perihelion distance of about 29.7 astronomical units (AU) and an aphelion distance of about 49.3 AU.
冥王星的轨道非常椭圆，近日点距离约为29.7天文单位（AU），而远日点距离约为49.3 AU。
The perihelion of Neptune occurs about every 165 years, making it the least frequent of all the planets in our solar system.
海王星的近日点大约每165年发生一次，这使得它成为我们太阳系中所有行星中最不频繁的一个。
The gravitational pull of Jupiter on Saturn is strongest at perihelion, influencing the latter's orbit significantly.
木星对土星的引力在近日点最强，显著影响了后者轨道。
The distance between the Earth and the asteroid belt is greatest during aphelion and smallest during perihelion.
地球与小行星带之间的距离在远日点时最大，在近日点时最小。
The orbit of Halley's Comet around the Sun has a perihelion distance of only 0.59 AU, making it one of the closest comets to the Sun.
哈雷彗星绕太阳运行的轨道近日点距离仅为0.59天文单位，使它成为距离太阳最近的彗星之一。
