the force that attracts a body toward the center of the earth, or toward any other physical body having mass. For most purposes Newton's laws of gravity apply, with minor modifications to take the general theory of relativity into account.

In a galaxy, the celestial bodies rotate around a central object. The Earth's galaxy is known as the Milky Way. Our solar system, made up of the Sun and the planets that encircle it, is a tiny part of that galaxy.]]> 2018-01-09 18:36:01 UTC https://padlet.com/3049921/lx3t84uzdwr/wish/219901441 Asteroid 3049921 https://padlet.com/3049921/lx3t84uzdwr/wish/219902248 An asteroid is a large, irregularly shaped object in space that orbits our Sun. If one of these giant rocks ends up on a collision course with Earth, we are in for big trouble. An asteroid is like a comet. ... Around a million asteroids are located between Mars and Jupiter in an area called the “asteroid belt.”]]> 2018-01-09 18:37:33 UTC https://padlet.com/3049921/lx3t84uzdwr/wish/219902248 Comet 3049921 https://padlet.com/3049921/lx3t84uzdwr/wish/219903402 a celestial body that appears as a fuzzy head usually surrounding a bright nucleus, that has a usually highly eccentric orbit, that consists primarily of ice and dust, and that often develops one or more long tails when near the sun.]]> 2018-01-09 18:39:42 UTC https://padlet.com/3049921/lx3t84uzdwr/wish/219903402 Planets 3049921 https://padlet.com/3049921/lx3t84uzdwr/wish/219904516 These discoveries challenged long-perceived notions of what a planet could be. ... This definition, which applies only to the Solar System, states that a planet is a body that orbits the Sun, is massive enough for its own gravity to make it round, and has "cleared its neighbourhood" of smaller objects around its orbit.]]> 2018-01-09 18:41:40 UTC https://padlet.com/3049921/lx3t84uzdwr/wish/219904516 Meteroid 3049921 https://padlet.com/3049921/lx3t84uzdwr/wish/219906098 Space is full of meteoroids. Most meteoroids are small, the size of pebbles or dust from a comet's tail, but they can also be quite large. They're all chunks off of something bigger, sometimes even the moon or Mars!
