How big would our Solar System be if the Sun was an eleven inch football/soccer ball? Alex and Jonathan set out to find the answer to this question, and visit each of the planets and planetoids along the way, all the way out to Eris.

Everything you could want to know about Mars, in 4K! Real HD photos and videos taken by rovers and orbiters around the Red Planet.
We discuss the orbit, climate, geographical features, polar ice caps of Mars, and a lot more. Have any questions? Post in the comments. If you did find this video interesting, please share it as it will help me be able to make more of these in the future.
SUBSCRIBE for more videos about our other planets.
All credit for the photos go to NASA and the ESA, and Calvin J Hamilton.
This is what our star - Sol. All videos are taken at different wavelengths (hence why the Sun is different colours than what you'd typically expect) to best show what's going on. For a detailed description of each of these videos, please click the links below.
