Planets (geography)

1) $**Mercury**$ :

< It is the smallest of the eight planets

< Strong magnetic field

2) $**Venus**$ :

< about the same size, mass and composition as Earth.

< Venus has the densest atmosphere of any body in the solar system.

< Due to the high temperature on the surface, liquid water is not possible on Venus

3) $**Earth**$ :

< It is the largest of the four inner planets in both mass and volume

< The surface of the earth is 71% covered with water in the form of seas and oceans, the rest consists of continents and islands.

4) $**Mars**$ :

< Mars is called the red planet but is actually more ocher in color.

< Like the Moon's, the surface is dotted with impact craters in some places

5) $**Jupiter**$ :

< Like Saturn, Jupiter is a gas giant, so it does not have a solid surface

< The mass of Jupiter is 2.5 times that of all the other planets of the solar system combined.

< The planet has the strongest magnetic field of any planet in the solar system

6) $**Saturn**$ :

< Saturn's atmosphere is over 96% hydrogen gas and just over 3% helium

< a gas giant

< It is the only planet in the solar system with a density less than water.

< rings

7) $**Uranus**$ :

< Uranus has the coldest atmosphere in our solar system with a minimum temperature of -224 degrees Celsius

< Uranus' atmosphere is 83% hydrogen, 15% helium, and 2% methane

< Uranus is a gaseous planet with no solid surface

8) $**Neptune**$ :

< The core consists of (molten) metal and rock and is surrounded by a mantle of rock, water, ammonia and methane

< blue color

< It is 17 times the mass of Earth
