Ever since the discovery of pluto in 1930 kids grew up learning that the solar system has nine planets.
Solar system uranus neptune pluto.
Almost all the planets travel around the sun in nearly perfect circles.
It takes an oval shaped path with the sun nowhere near.
Neptune minus 331 f 201 c pluto minus 388 f 233 c this graphic shows the average temperatures of various destinations in our solar system.

The solar system is the gravitationally bound system of the sun and the objects that orbit it either directly or indirectly.

That all changed in the late 1990s when astronomers started arguing about whether pluto.
Pluto is a dwarf planet that lies in the kuiper belt an area full of icy bodies and other dwarf planets out past neptune.
Venus is an exception because its dense atmosphere acts as a greenhouse and heats.
Neptune neptune was the first planet discovered through mathematical calculations rather than observation.

Beyond neptune a newer class of smaller worlds called dwarf planets reign including longtime favorite pluto.
Of the objects that orbit the sun directly the largest are the eight planets with the remainder being smaller objects the dwarf planets and small solar system bodies of the objects that orbit the sun indirectly the moons two are larger than the smallest planet.
Planets not to scale in general the surface temperatures decreases with increasing distance from the sun.
Uranus uranus is tipped on its axis by almost 90 degrees.
Pluto is very small only about half the width of the united states and its biggest moon charon is about half the size of pluto.
