The Earth. By Miss O. 3 rd planet from the Sun . 1 of 4 rocky planets. not a considered a planet at this time. About 150 million kilometers from Sun (93 million miles away). Five Things Make the Earth a “Habitable Planet” in the Universe!.

1. The Earth’s distance from the sun is just right. The sun warms the Earth, and it is not too hot or too cold—it is just right.
Diameter is the distance across the center of a round object.
2. The size of the Earth is perfect for maintaining the gravity we need so we don’t float away or get crushed. We can walk and run with ease. Many other planets don’t have the right amount of gravity for us to live there.
Gravity is a force that pulls two objects together.
To scale video
It would take 109 Earths to stretch across the Sun, and it would take over one million Earths to "fill up" the Sun if it were hollow.
3. The Earth’s tilt on its axis is ideal for life.a. If it were tilted any more, the temperature would swing too much between super-hot summers and super-cold winters.b. If it were tilted any less, too much sunshine all year long would super-heat the equator and too little heat would reach the north and south regions.
An axis is an imaginary line that runs through the center of a planet or other object.
With a white board, you will write whether the Northern Hemisphere is experiencing winter or summer.
5. Liquid water is necessary for life to exist. The Earth is the only planet (we know of) with enough liquid water—consider the oceans, lakes, rivers, and streams.
An atmosphere is the blanket of gases that surrounds a planet or moon.
