The Solar System

A great thing

The Sun

The sun is the star at the center of the solar system. The sun is about 109 times bigger than the earth. Chemically, about three quarters of the Sun's mass consists of hydrogen, while the rest is mostly helium. 

The Moon

It is the second brightest object in the solar system besides the sun. The moon was formed 4.5 billion years ago. The Moon is the second densest satellite in the Solar System after.

Mercury

Mercury is the innermost planet of the solar system. The planet is named after a Roman god of the messengers. Mercury's axis has the smallest tilt of any of the Solar System's planets.

Venus

Venus is the second planet form the sun. Venus is named after a Roman goddness so love and beauty. Vennus is sometimes called Earth's "sister planet."

Earth

We live on planet earth. We are the only one that has life on it , that we know of right now. Earth has 6 billion people living on it. Earth was named after GAIA the greek goddness.

Mars

Mars was named after the greek god of war. The first spacecraft that visted Mars in 1965 was Mariner 4. There has been a lot of sapcecrafts that has visted Mars in the past 48 years.

Jupiter

 Jupiter was named after the greek god Zeus and zeus was the god of gods and goddness. Jupiter is the fourth brightest oblect on the sky. Jupiter has a giant red spot and it is call the Giant Red Spot.

Saturn

Saturn was named after the greek god Cronus. Saturn is the second largest planet in our solar system. Saturn has 53 named satellites.

Uranus

Uranus is the ancient Greek deity of the Heavens, the earliest supreme god. people believe that uranus is made of ice and water. Uranus is a light blue color almost baby blue.

Neptune

In Roman mythology Neptune (Greek: Poseidon) was the god of the Sea. Neptune is the eighth planet from the Sun and the fourth largest. Neptune's blue color is largely the result of absorption of red light by methane in the atmosphere but there is some additional as-yet-unidentified chromophore which gives the clouds their rich blue tint.

Pluto

Pluto orbits beyond the orbit of Neptune (usually). It is much smaller than any of the official planets and now classified as a "dwarf planet". In Roman mythology, Pluto is the god of the underworld. Pluto has been assigned number 134340 in the minor planet catalog.

Comets

A comet is an icy small Solar Systen body that, when close enough to the Sun, displays a visible sometimes called a tail. Both the coma and tail are illuminated by the Sun and may become visible from Earth when a comet passes through the inner Solar System. The streams of dust and gas each form their own distinct tail, pointing in slightly different directions.

Meteors

A meteors is also called a shooting star. Meteors mostly occur in the mesophere at altitudes between 76 km to 100 km. Meteors have roughly a fifty percent chance of  happending in daylight on the earth.

Red Giant

A red giant is a luminous giant star of low or intermediate mass in a late phase of stellar evolution. The most common red giants are the so-called red giant branch.

Supernova

A supernova is a stellar explosion that is more energetic than a nova. Supernovae are extremely luminous and cause a burst of radiation that often briefly outshines an entire galaxy, before fading from view over several weeks or months.

White Dwarf

They are very dense; a white dwarf mass is comparable to that of the Sun, and its volume is comparable to that of the Earth. The nearest known white dwarf is Sirius B, 8.6 light years away. White dwarfs are thought to be the final evolutionary state of all stars whose mass is not high enough to become a neutron star.

Asteroids

Several hundred thousand asteroids have been discovered and given provisional designations so far. Some asteroids are bigger than planets and moons.

cepheid variable

A Cepheid is a member of a class of very luminous variable stars. Cepheid variables are divided into several subclasses which exhibit markedly different masses, ages, and evolutionary histories.

The Big Dipper

The Big Dipper, also known as the Plough or the Saptarishi. Is an asterism of seven stars that has been recognized as a distinct grouping in many cultures from time immemorial. The component stars are the seven brightest of the formal constellation Ursa Major.
