The planet with the strongest gravitational attraction at its surface is Jupiter. Although Saturn, Uranus, and Neptune are also very massive planets, their gravitational forces are about the same as Earth. This is because the gravitational force a planet exerts upon an object at the planet's surface is proportional to its mass and to the inverse of the planet's radius squared.
A Day on Each of the Planets
A day is the length of time that it takes a planet to rotate on its axis (360°). A day on Earth takes almost 24 hours.
The planet with the longest day is Venus; a day on Venus takes 243 Earth days. (A day on Venus is longer than its year; a year on Venus takes only 224.7 Earth days).
The planet with the shortest day is Jupiter; a day on Jupiter only takes 9.8 Earth hours! When you observe Jupiter from Earth, you can see some of its features change.

在行星中引力最强的为木星。尽管土星、天王星和海王星的体积也很大，但他们的引力仅与地球相当。这是因为行星对其表面物体施加的引力与其质量成正比而与其半径的平方成反比。
各个行星上的一日
一日是行星绕其自转轴旋转（360°）所需的时间长度。地球上的一日接近24小时。
在各个行星中，金星上的一日时间最长。金星上的一日等于243地球日。（金星上的一日比一年要长，金星上的一年只需要224.7地球日）
在各个行星中，木星上的一日时间最短。木星上的一日只需要9.8小时！当你从地球上看木星时，你会发现它的一些特征正在变化。
行星的平均轨道速度
环绕太阳运行的各个行星的轨道速度是不同的。每颗行星在靠近太阳时运行速度会加快而在远离太阳时运行速度会变慢。（这是开普勒的行星运动第二定律）
