=========================================
The speed of light in a vacuum is exactly 299,792,458 metres per second.
We live on a planet in our solar system, eight light minuts away from the sun.
Our sun is four light years away from our nearest star.
In our galaxy there are about 200 billions of stars.
Nearest galaxy is 2 million light years away.
Our group of galaxies is called the local group, containing over 30 galaxies.
This “local group” covers over 10 million light years in diameter.
The “local group” belongs to the Virgo supercluster of galaxies.
The Virgo supercluster is about 200 million light years in diameter.
The Great attractor is a “gravitational anomaly” somewhere in the Virgo supercluster, pulling the other galaxy groups towards the Hydra and Centaurus constellations.
