Examining more galaxies still, they found that their rotation curves – the orbital speed of visible stars within the galaxy compared with their radial distance to the galaxy centre – contradicted ...

Mercury’s average orbital speed is about 47.36 kilometers per second. That’s roughly 106,000 miles per hour! To put that in perspective, a commercial airplane cruises at around 550 miles per hour.

When a SpaceX Dragon vehicle returns a crew of astronauts, the vehicle has to be slowed down from its orbital speed of 17,500 miles per hour to about 350 miles per hour, when its small “drogue ...

Naturally, the closest approach is in January. In terms of the seasons, distance from the sun is way less important than the tilt. But, like the rest of us, the Earth slows down a bit in July. The ...
