If you were to throw a ball on another planet, how far would it go? Your arm strength would make some, perhaps minuscule, difference since the gravity of the question lies in its — ahem — gravity.
In this video by Dr. James O’Donoghue, an astronomer at JAXA (Japan Aerospace Exploration Agency), you can see an excellent data visualization showing how far a ball thrown at a 45° angle would travel on various celestial bodies with differing gravitational pulls in the solar system as well as the moon and Pluto. Keep in mind that O’Donoghue assumes no atmospheric resistance for his calculations and a starting speed of 45 mph (72.4 km/h) for the ball. Overall, the video might make you feel excited about the future of sports on other planets — or make you daydream about playing fetch with your dog on the moon in the future. If you want to see the visualization, make sure you watch the video embedded above, and as always, enjoy!

The system, which uses Tesla technology, went online earlier than originally planned due to predicted energy shortages.
