Brandons blog: SPACE

For my blog I'm going to talk about space and our solar system. I'm going to tell you about what a planet is and the difference between a inner planet and a outer planet. I will compare and contrast a period of revolution and a period of rotation. I will tell you much more about the space and our solar system and how it works.

Planets are celestial body's that orbit around a star. Inner planets are different from the the outer planets because the inner planets are made out of rocks, minerals, and metals similar to the Earth. The Inner Planets are Mercury, Venus, Mars, and Earth. The Outer Planets are mostly trapped gases like Helium, Hydrogen, and water and they are just the rest of the planets in our solar system except Pluto.

A period of rotation is the amount of time for an object to rotate on its axis. A period of revolution is the amount of time when something orbits around an object. They are similar by rotating around something and rotation is different because it means to rotate on something but revolution means to rotate around something.

Dwarf planets are similar to planets because to be dwarf planet it would have to be orbiting something and be almost round like a planet. Dwarf planets are different from planets by their shape and size because dwarf planets are smaller than planets and are not usually round as the planets.

A planet's shape of an orbit is elliptical. Elliptical is a curved shape and the obits shape can be a oval. Planets orbit the sun by the sun's gravitational pull and nothing really can stop it because the gravitational pull is so strong. The closer the planet is to the sun the faster the orbit is because the planet would have to travel a less distance and the planets farther away obits slower because it has a much longer distance to travel.Asteroids are rocks orbiting the sun and are made out of minerals and rocks. Comets are body's that contain ice and dust that go extremely fast.
