Motion interpolation of seven images of the HR 8799 system taken from the W. M. Keck Observatory over seven years, featuring four exoplanets. This is a list of extrasolar planets that have been directly observed, sorted by observed separations. This method works best for young planets that emit infrared light and are far from the glare of the star.
On it, Porco encouraged the world to celebrate life on planet Earth and humanity's accomplishments in the exploration of the Solar System. Astronomers Without Borders coordinated events internationally. [8] NASA spearheaded a related event called 'Wave at Saturn' "to help acknowledge the historic interplanetary portrait as it is being taken". [9]
The Solar System Family Portrait is an image of many of the Solar System's planets and moons acquired by MESSENGER during November 2010 from approximately the orbit of Mercury. The mosaic is intended to be complementary to the Voyager 1 ' s Family Portrait acquired from the outer edge of the Solar System on February 14, 1990.

The best available theory of planet formation is the nebular hypothesis, which posits that an interstellar cloud collapses out of a nebula to create a young protostar orbited by a protoplanetary disk. There are eight planets within the Solar System; planets outside of the solar system are also known as exoplanets.
The orbits of Solar System planets are nearly circular. Compared to many other systems, they have smaller orbital eccentricity. [70] Although there are attempts to explain it partly with a bias in the radial-velocity detection method and partly with long interactions of a quite high number of planets, the exact causes remain undetermined. [70] [74]
