Formation and evolution of the Solar System timescale of their formation. At the current locations it would have taken millions of years for their cores to accrete. This means that Uranus and Neptune may have formed closer to the Sun—near or even between Jupiter and Saturn—and later migrated or were ejected outward (see Planetary migration below). Motion in the planetesimal era was not all inward toward the Sun; the "Stardust" sample return from Comet Wild 2 has suggested that materials from the early formation of the Solar System migrated from the warmer inner Solar System to the region of the Kuiper belt.

Planet Lofoten In Montreal, Canada in 2007 and has since then been shown at several galleries around the world including The Louvre. Planet Lofoten Planet Lofoten is a Land Art Installation of the solar system positioned in the open nature of West Lofoten in Northern Norway. The Planets are made from stone and range in size from Jupiter at several hundred kilograms to Pluto at only a few grams, and ranges within an area of 30 km from Reine at Moskenes Island to Nordland at Værøy Island. The Sun is still in the construction process and will be a 7-meter diameter sphere
