Ever wondered just how fast we are moving through space?
Well, the Earth revolves around the Sun at around 30 km/sec, in its annual path, which takes a year to complete.
The Solar System revolves around the Milky Way centre at around 230 km/sec. It takes around 225 million years to complete a single revolution.
The Milky Way is the second largest galaxy in the Local Group, the Andromeda Galaxy being the largest.
The Local Group is part of the Virgo Supercluster, which itself is part of the Laniakea Supercluster. This is HUGE!!!
Consequently, the Earth is always travelling through new space has never occupied the same point in space twice! Ever!!!
The velocity of the Earth through space is around 370 km/sec relative to the Cosmic Microwave Background. The CMB is an echo of the Big Bang and is used as a ‘reference’ point for the universe.
In the time taken to read this the Earth has travelled more than 10,000 km!
Wow!
