The Sun
The Sun is one out of billions of stars. The Sun is the closest star to Earth. The Sun rotates once every 27 days.
The Sun is now a middle-aged star, meaning it is at about the middle of its life. The Sun formed over four and a half billion
years ago. You may think the Sun will die soon, but it will keep shining for at least another five billion years.
Mercury
Mercury is the innermost and smallest planet in the Solar System
. orbiting the Sun once every 87.969 Earth days.
Venus Venus is known as Earths' twin sister because of its similar size
and proximity to each other.Its atmosphere is made up mostly of carbon dioxide.
Earth
The Earth is not actually round in shape; in fact it is geoid. This simply means that the rounded shape has a s
light bulge towards the equator.
Mars
Mars has the largest canyon in the solar system. It would reach from Los Angeles to Chicago if it was on Earth! Mars has a very
thin atmosphere, mostly carbon dioxide, but dust storms can cover the whole planet for months at a time. About every two
years the Earth and Mars come close together. The planet has two moons, Deimos and Phobos.
Jupiter
Jupiter takes about 12 years to orbit the sun and rotates in about 10 hours. This short Jupiter "day" is
amazing since the planet is roughly 11 Earth diameters wide. Unlike the rocky planets, Jupiter is a ball of
dense hydrogen, helium, water, nitrogen and other gases over a tiny rocky core. Powerful winds dominate
the atmosphere with criss-crossing jet streams, lightning and huge hurricane-like storms like the Great
Red Spot.
Saturn
The icy planet Uranus is a smaller version of Jupiter and not the small rocky bodies like Earth. It have faint rings and a number of
moons. Uranus takes some 84 years to orbit the sun. It rotates on its side and so half the time one pole is toward the sun and then the other making each of the four seasons last about 20 years.
The faint bluish color of the planet is because the methane gas in
the atmosphere absorbs red light and reflects blue light.
UranusNeptune is the eight planet from the Sun in our solar system. Here are collection of fact about Neptune availab
le to us through astronomy and scientific research.

Pluto
Pluto is the farthest planet from the Sun and by far the smallest.
Pluto is smaller than seven of the solar systems moons
