There are eight known planets orbiting our sun, including Earth. Making a model is a fun introduction to this solar system, and a good art project for primary school science classes. This detailed example can take a few hours to make, but most of that involves waiting for paint or clay to dry.

[pdf] The solar system comprises 8 planets, approximately 170 natural planetary satellites (moons), and countless asteroids, meteorites, and comets. What are the planets in the solar system?. .
Located at the centre of the solar system and influencing the motion of all the other bodies. .
All the planets and dwarf planets, the rocky asteroids, and the icy bodies in the Kuiper belt move around the Sun in elliptical orbits in the same direction that the Sun rotates. This motio. .

[pdf] A dwarf planet is a small that is in direct orbit around the , enough to be , but insufficient to achieve like the eight classical of the . The prototypical dwarf planet is , which for decades was regarded as a planet before the "dwarf" concept was adopted in 2006.
[pdf] All four of the innermost, rocky planets of the may have had large variations of their obliquity in the past. Since obliquity is the angle between the axis of rotation and the direction perpendicular to the orbital plane, it changes as the orbital plane changes due to the influence of other planets. But the axis of rotation can also move (), due to torque exerted by the Sun on a planet's equatorial bulge. Like Earth, all of the rocky planets show axial precession.
[pdf] Astronomers sometimes divide the Solar System structure into separate regions. The includes Mercury, Venus, Earth, Mars, and the bodies in the . The includes Jupiter, Saturn, Uranus, Neptune, and the bodies in the . Since the discovery of the Kuiper belt, the outermost parts of the Solar System are considered a distinct.
