Did you know: time and space

This month ….. the incredibly quick to the incredibly long and everything in between

It takes the Sun 225 million years to travel once around the centre of the Milky Way Galaxy. This is known as a galactic year or a cosmic year.

A Pulsar is a neutron star that spins incredibly fast. The fastest known spinning pulsar, PSR J1748-2446ad, spins once every 1.4 milliseconds which is 716 times per second, or 42,960 times a minute.

It takes a photon of light only eight minutes to reach Earth from the Sun, but it can take 100,000 years for that photon to travel from the core of the Sun to the surface, the photosphere, where it bursts out and flies at the speed of light

Since it was discovered 89 years ago in 1930 we have not seen Pluto complete one orbit around the Sun. At an average distance of 5.9 billion km it takes Pluto 248 Earth years to go once around the Sun. Meanwhile, Mercury, the closest planet, zips around the Sun in 88 days.

The speed of light travelling in the vacuum of space at 300,000 km per second is the fastest that anything can go…. despite what happens on Star Trek!
