My presentation about Solar System

This is my presentation about the Solar System:

The Solar System: The Solar System is the gravitationally bound system comprising the Sun and the eight planets that orbit it. Other objects, like dwarf planets or small Solar System bodies, are part of it too.

The Solar System formed 4.6 billion years ago from the gravitational collapse of a giant interstellar molecular cloud.

Where it is?: We all know our solar system is part of the Milky Way, but… where is it exactly? Well, this is not the most accurate measurement, but it is thought to be, more or less, here (señala).

The Sun:The Sun is the Solar System's star and by far its most massive component. Its large mass sustains nuclear fusion of hydrogen into helium, making it a main-sequence star.

Planets: As said before, the Solar System counts with eight planets. Some of them are small and rocky, while others are vast and made of gases. They all orbit the Sun, obviously. Let's take a look.

Mercury: Mercury is the closest planet to the Sun and the smallest planet in the Solar System. Its name comes from the roman god of the traders, thieves and travelers (in the greek mythology he is known as Hermes).

Venus: Venus is close to size to Earth but it is much drier than it. Its name comes from the Roman goddess of love and beauty (her greek form is Aphrodite).

Earth: Earth is the largest and densest of the inner planets, the only one known to have current geological activity, and the only place where life is known to exist. It has one natural satellite, the Moon.

Mars: Mars is the fourth planet of the Solar System and the second smallest one, after Mercury. It’s named after the Roman god of the war (who is also called Ares by the greeks). It has two moons, Phobos and Deimos, whose names come from the gods two sons.

Jupiter: Jupiter is 2.5 times the mass of all the other planets put together. It’s named after the roman god of the storms, the lord of the gods (in the greek mythology, Zeus). Jupiter has 67 known satellites.

Saturn: Saturn is the sixth planet of the Solar System and the second largest one, following the huge Jupiter. It is named after the Roman god of agriculture, the first one in the Capitol (known as Cronus in the greek mythology).

Uranus: Uranus is the lightest of the outer planets. Uniquely among the planets, it orbits the Sun on its side. It has a much colder core than the other giant planets. Uranus has 27 known satellites. Its name comes from the Greco-roman god of the sky.

Neptune: Neptune is the eighth planet of the Solar System. Named after the Roman god of the sea (or the greek Poseidon), this is the most distant planet, so far away of the Sun.

Dwarf planets: A dwarf planet is a small planet. The dwarf planet Pluto is the largest known object in the Kuiper belt. It was considered to be the ninth planet. Charon(the biggest moon) is officially classified as a moon of Pluto.

Satellites: In the Solar System, there are 181 known natural satellites, or moons. Not all the solar bodies have their own moons (Mercury and Venus, for example). The most famous one is Earth’s Moon.

Asteroids: Asteroids are classified as small Solar System bodies and are composed mainly of  rocky and metallic minerals, with some ice. The asteroid belt occupies the orbit between Mars and Jupiter.

Comets: A comet is an icy small Solar System body that, when passing close to the Sun, heats up and begins to outgas, displaying a visible atmosphere or coma, and sometimes also a tail.

The Kuiper Belt: The Kuiper belt is a great ring consisting mainly of objects composed of ice. It is estimated to contain thousands of dwarf planets, it is composed mainly of small Solar System bodies. Many of the larger Kuiper belt objects, (Quaoar, Varuna, Orcus) may be dwarf planets.

Artificial satellites: Artificial satellites are human made Solar System bodies, which orbit planets in order to get information about our system. Of course, they are used for other aims, but this is the main one. The first artificial satellite was Sputnik.
