Mercury Mercury is the closest planet to the
Sun. Mercury orbits at 29 miles per second. Temperatures range from 700 degrees
to –300 degrees Fahrenheit.

Earth Earth is the third planet from the Sun. Earth has oceans of water, and an
oxygen-rich atmosphere. Earth has intelligent life. The distance from the surface to the
center of the Earth is about 2,000 miles.
Our home planet

Mars Mars is the fourth planet from the Sun. Mars is smaller and colder than Earth. Temperatures range from 30 degrees
to –220 degrees Fahrenheit.
Our nearest neighbor.

Jupiter Jupiter is the fifth planet from the Sun. Jupiter is the largest planet in the solar
system. Jupiter’s fast rotation causes the
clouds to form bands. Big red spot in southern hemisphere is
a hurricane-like storm.
Starts with a J.

The planet Jupiter's four largest moons are called the Galilean satellites, after Italian astronomer Galileo Galilei, who observed them in 1610.
These large moons are Io, Europa, Ganymede, and Callisto.
Ten of the Moons of Jupiter:
1. Metis
2. Adrastea
3. Amalthea
4. Thebe
5. Io
6. Europa
7. Ganymede
8. Callisto
9. Themisto
10. Leda
The German astronomer Simon Marius claimed to have seen the moons around the same time, but he did not publish his observations and so Galileo is given the credit for their discovery.

Saturn Saturn is the sixth planet from the
Sun. Saturn is known as the “ringed”
planet. Rings are made of ice and rock. Winds at the equator reach speeds of
1,100 miles per hour.
Starts with S.

Uranus Uranus is the seventh planet from the
Sun. Uranus is the third largest planet in
the solar system. Named after the father of Saturn in
Roman mythology. Summers and winters on Uranus last
42 years.

Neptune Neptune is the eighth planet from the
Sun. Neptune is the fourth-largest planet in
the solar system. Neptune is sometimes further from the
Sun than Pluto.

Is a ball of hot gases. Is 70% hydrogen, 28% helium, 1.5%
carbon, nitrogen, and oxygen, and 0.5% all other elements.
The Sun's temperature is 10,000 degrees Fahrenheit at the surface and 27,000,000 degrees Fahrenheit at the center.

The average distance from the Earth to the Sun is 93,000,000 miles. It takes light eight and a half minutes to travel from the Sun to the Earth.
The diameter of the Sun is 870,000 miles, 109 times larger than the Earth's. Its volume is big enough to hold over 1 million Earths.

Scientists study the sun with instruments on the Ulysses spacecraft.
Ulysses is a joint effort of NASA and the European Space Agency.
Ulysses was launched in October 1990. It is the first spacecraft to orbit the Sun's
North and South poles.
