where is helium 3 found on the moon
Helium-3 The abundance of helium-3 is thought to be greater on the Moon than on Earth, having been embedded in the upper layer of regolith by the solar wind over billions of years,[4] though still lower in abundance than in the solar system's gas giants.[5][6]
Moon The lighter-coloured regions of the Moon are called terrae, or more commonly highlands, because they are higher than most maria. They have been radiometrically dated to having formed 4.4Â billion years ago, and may represent plagioclase cumulates of the lunar magma ocean.[61][62] In contrast to Earth, no major lunar mountains are believed to have formed as a result of tectonic events.[72]
