Also know, how does our solar system travel through space?
The planets orbit the Sun, roughly in the same plane. The Solar System moves through the galaxy with about a 60° angle between the galactic plane and the planetary orbital plane. The Sun appears to move up-and-down and in-and-out with respect to the rest of the galaxy as it revolves around the Milky Way.
Simply so, how fast is the solar system moving through space?
828,000 km/h
We orbit the centre of the Milky Way about once every 240 million years. However, the universe has been expanding ever since the big bang, about 13.8 billion years ago. All galaxies are moving away from each other at a speed proportional to the distance that separates them.
