• 225 million years -- time since end of Permian Period (end of Palaeozoic Era) and beginning of TriassicThe Triassic is a Geologic period that extends from about 248 to 202 million years (My or 'megayears') before the present. The extinction event that closed the Triassic period has recently been more accurately dated, but as with most older geologic period Period (beginning of Mesozoic Era)
• 226 million years -- time it takes the solar systemA generic solar system (or planetary system consists of at least one star and various orbiting objects (such as asteroids, comets, moons, and planets). The term originated to describe the planetary system around Sol, the Latin name for our sun. The planet to complete one rotation around the center of the Milky WayThis article is about the galaxy called the Milky Way. For the candy bar of the same name, see Milky Way candy bar. The Milky Way (a translation of the Latin Via Lactea in turn derived from the Greek Galaxia gala, galactos means "milk")) is a hazy band of

As with most older geol and beginning of Permian Period
