The astronomical unit (symbol: au, or AU or AU) is a unit of length, roughly the distance from Earth to the Sun and approximately equal to 150 million kilometres (93 million miles) or 8.3 light-minutes. The actual distance from Earth to the Sun varies by about 3% as Earth orbits the Sun, from a maximum (aphelion) to a minimum (perihelion) and back again once each year.

WebJan 31, 2015 · Since then, the comet's perihelion has stood at about 1.3 AU, which is about 27 million miles (43 million kilometers) outside Earth's orbit. The comet's nucleus is thought to be quite porous, giving it a density much lower than that of water. When heated by the Sun, it is thought to emit about twice as much dust as gas.
