    In planetary astronomy, a centaur is a small Solar System body that orbits the Sun between Jupiter and Neptune and crosses the orbits of one or more of the giant planets. . Centaurs generally have unstable orbits because of this; almost all their orbits have dynamic lifetimes of only a few million years, [1] but there is one known centaur, 514107 Kaʻepaokaʻawela, which may be in a stable ...

    Evolution of the solar luminosity, radius and effective temperature compared to the present-day Sun. After Ribas (2009) [3] The uncrewed SOHO spacecraft was used to measure the radius of the Sun by timing transits of Mercury across the surface during 2003 and 2006. The result was a measured radius of 696,342 ± 65 kilometres (432,687 ± 40 miles).
