The Solar System By: Valeria López, Ana Sofía Mendoza, Antonio

Campolongo & Miguel Macedo.

The Sun and all the planets that orbit it form the Solar System. The Solar System contains eight planets and

their satellites, and a large number of comets.

Our Solar System is part of the Milky Way Galaxy.

The Solar System consists of the Sun and those celestial objects bound to it by gravity, all of which formed from

the collapse of a giant molecular cloud approximately 4.6 billion years ago.

The Solar System is also home to two regions populated by smaller objects: The asteroid belt and trans-Neptunian objects, composed mostly of ices such as water, ammonia

and methane.

The SunIs the principal component of the Solar System, is a star, it gives off heat and light. Is made up of gases, it’s bigger than all the planets in the solar system, more than 100 times bigger than Earth.

The sun is not particularly large for a star, it looks bigger than other stars because is nearer

to Earth.

THE PLANETS

Ceres, Pluto, Haumea, Makemake and Eris, are recognized to be large enough to have been rounded by

their own gravity, and are called “thus termed dwarf planets”.

All the planets that orbit the solar system are called celestial bodies, this planets revolve around the Sun, increasing distance from the Sun. The planets are:

•Mercury•Venus•Earth•Mars•Jupiter•Saturn•Uranus•Neptune

Mercury: Is much smaller than the Earth. It has the shortest orbit around the Sun.

Venus: Is similar in size to Earth. It’s the brightest planet. It’s surface has the highest temperatures .

Earth: Is the only planet in the Solar System where there is life.

Mars: Is an intense red color. It is full of craters and volcanoes. Some of these volcanoes are bigger than any mountain on Earth.

Jupiter: Is the biggest planet in the Solar System. It has a red spot on it’s surface.

Saturn: Is surrounded by thousands of rings. These rings are made up of millions of small particles.

Uranus: It has a characteristic blue-green color.

Neptune: Is the farthest planet from the Sun. It’s blue.
