Some space things I've seen posted on other boards
- "Earth is at constant 1,675 km/h spin around its axis, which is as fast as F-15 Eagle jet fighter rushing to intercept enemy aircraft or more than 4 times the maximum speed of F1 racing car."
- "8 minutes and 19 seconds is the time it takes for light emitted by the Sun to voyage 150 million kilometers through cosmic ocean to reach Earth.
Given that speed of light is 300,000 km/s, it takes 2 years for light to get across the domain of our Solar System."
- "Our Sun is one out of 200-400 billion stars in Milky Way galaxy.
To get across our galaxy it would take us 100,000 to 120,000 years, given that our spacecraft would be able to travel as fast as light."
- "In this journey we would visit 200 to 400 billion planets with 10 billion of them being lodged in the habitable zone just as our home planet Earth."
- "Our Sun carrying Earth and the rest of the planets, orbits the super massive black hole in the center of Milky Way at the speed of 220 km/s, completing full revolution every 225-250 million years. Therefore since its birth 4.57 billion years ago Sun has completed 20 to 25 laps around the orbit of our galactic center."
- "Milky Way is 1 out of 54 galaxies making up Local Galactic Group with its gravitational center resting somewhere in between Milky Way and Andromeda Galaxy. The mutual pull of the two giants will force the inevitable collision in about 4 billion years from now."
- "The Local Galactic Group has a mind boggling 10 million light years diameter and estimated velocity reaching 69 km/s."
- " Local Group itself is part of Virgo Supercluster containing around 100 galactic groups and clusters in its range. It is approximately 7000 times larger than Local Group and about 100 billion times that of Milky Way."
- " Superclusters can further bound into thread-like complexes to create largest known cosmic structures called Galaxy Walls. Sloan Great Wall is the largest of these gigantic cosmic wonders and has imposing domain stretching 1.37 billion light years across. It is situated roughly 1 billion light years away from the Blue Planet we all call home."
- " It is little known about the far reaches of the universe, however it is known that it can be observed 46 billion light years to any direction and harbor roughly 80 billion galaxies."

Way too much to post and take in for one post so those will have to do for now
