The solar system has one star, eight planets, five dwarf planets, at least 290 moons, more than 1.3 million asteroids, and about 3,900 comets. It is located in an outer spiral arm of the Milky Way galaxy called the Orion Arm, or Orion Spur. Our solar system orbits the center of the galaxy at about 515,000 mph (828,000 kph). It takes about 230 million years to complete one orbit around the galactic center.

We call it the solar system because it is made up of our star, the Sun, and everything bound to it by gravity - the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune; dwarf planets Pluto, Ceres, Makemake, Haumea, and Eris - along with hundreds of moons; and millions of asteroids, comets, and meteoroids.

10 THINGS about our solar system

Saying Farewell: Which Spacecraft are Leaving Our Solar System?

Only two spacecraft have reached interstellar space, the space between stars. Three other spacecraft have achieved enough velocity to eventually travel beyond the boundaries of our solar system.

Voyager 1 went interstellar in 2012 and Voyager 2 joined it in 2018. Both spacecraft, launched in 1977, are still in communication with Earth.

NASA's New Horizons spacecraft is currently exploring an icy region beyond Neptune called the Kuiper Belt. It eventually will leave our solar system.

Pioneer 10 and Pioneer 11 also will ultimately travel silently among the stars toward the galactic core. The spacecraft used up their power supplies decades ago.

Conventional paper airplane. Pattern entered by Scott Pakin.

Move Fold Percent slowly for this pattern to fold correctly!

When this pattern is triangulated (during the setup of the simulation) it forms many skinny triangles, these triangles are very unstable as the pattern folds.

Designed by Kendrick Feller based on the Spidron Tessellation by Daniel Kwan and similar spiral tessellations by Ekaterina Lukasheva.

Designed by Elod Beregszaszi, original patterns available at Popupology.

Designed by Ullagami, original pattern available at Ullagami.

This file was generated by Polygami, an app by Shahul Alam, Lauren Huang, and Mahi Shafiullah that creates crease patterns for any 2D arrangement of voxels on a square grid.

Allow this pattern to fold, then select Allow User Interaction (Advanced Options right menu) and drag the central vertex to pop into into an alternate, inverted configuration.

Original design by Emmanuel Mooser. Crease pattern corrected and modified for rigid origami by William Gardner.

Based on Flower Tower design by Chris K. Palmer. Crease pattern files generated by William Gardner.

Designed by Goran Konjevod. Try folding these to ~65% and letting them settle to a curved shape.
