The document summarizes the nine planets in our solar system. It provides details about each planet's composition, size, orbit time, moons, and other characteristics. The planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto (no longer considered a planet). The Sun sits at the center of the solar system with the planets orbiting in circular paths around it in the same direction.

2. There are nine planets in our
Solar System that circle
around our Sun. The Sun sits in
the middle while the planets
travel in circular paths
(called orbits) around it. These
nine planets travel in the same
direction. The solar system is
made up of two
parts: The inner solar system
and the outer solar system.

and other elements.
. Over 300000 times larger
than earth
. About 1.4 million kilometers in
diameter
. All planets orbit around Sun

ago
.The Earth's atmosphere is 77%
nitrogen, 21% oxygen, with

. Consist of carbon dioxide,
nitrogen argon

8. Jupiter.Largest planet in the Solar System
. Named for the king of ancient roman
gods

and water.
. Orbits the sun once in every 12 years
. Have 64 moons
. Giant ball of gas
. The giant red spot is a storm that has
lasted for over 100s of years

9. Saturn

.2nd
largest planet.
. Named after roman god of
agriculture

10. Uranus
.3rd
largest planet in the solar
system
.Named after roman god who was
the father of titans
.Gas planet like Neptune, Saturn
.Has at least 27 moons
. Uranus takes some 84 years to
orbit the sun
. The bluish is because the methane
gas in the atmosphere absorbs
red light and reflects blue light

11. Neptune.Named after the roman sea god
.Has 13 moons
.The methane gas gives the planet blue
color because the gas absorbs red light
and reflects the blue back into space

century
