What is Earth's place in the Universe? by Janis Jaramillo https://padlet.com/janisjjg12/solar_system The Universe contains countless billions of stars grouped in galaxies. One of those stars is our Sun. The Sun and all the planets, and other bodies around it make up our Solar System. en-us 2021-10-31 20:24:26 UTC 2023-04-05 07:25:27 UTC hello@padlet.com janisjjg12 https://padlet.com/janisjjg12/solar_system/wish/1857171658 In the Universe, a supercluster is a group of galaxies held together by gravity. Earth is located in the universe in the Virgo Supercluster of galaxies. Within a supercluster, there is a smaller group of galaxies called the Local Group. Earth is in the second-largest galaxy of the Local Group - a galaxy called the Milky Way.

Earth is located in one of the spiral arms of the Milky Way (called the Orion Arm) which lies about two-thirds of the way out from the center of the Galaxy. Here we are part of the Solar System - a group of eight planets, as well as numerous comets and asteroids, and dwarf planets that orbit the Sun. We are the third planet from the Sun in the Solar System.]]> 2021-10-31 20:36:08 UTC https://padlet.com/janisjjg12/solar_system/wish/1857176229 janisjjg12 https://padlet.com/janisjjg12/solar_system/wish/1857177083 2021-10-31 20:37:01 UTC https://padlet.com/janisjjg12/solar_system/wish/1857177083 janisjjg12 https://padlet.com/janisjjg12/solar_system/wish/1857177347 2021-10-31 20:37:19 UTC https://padlet.com/janisjjg12/solar_system/wish/1857177347 janisjjg12 https://padlet.com/janisjjg12/solar_system/wish/1857184122 Earth's solar system is part of the Milky Way Galaxy, which is one of many galaxies in the Universe. The planet Earth is a tiny part of a vast universe that has developed over a span of time beginning with a period of extreme and rapid expansion.

Earth's solar system consists of the Sun and other objects that are held in orbit around the Sun by its gravitational pull on them. Motions within the Earth-Moon-Sun system have effects that can be observed on Earth.
