[HOT] : How long would it take for a bullet from different planets to reach the surface?

You must have learned that if you went to the moon you would weigh a sixth of your weight on earth. You may also know that if you weighed 100 kilograms on Earth, you would weigh only 38 kilograms on Mars. But what about the rest of the planets in the solar system? And the sun ? While using your weight percentage as a comparison tool is great, comparing your weights on major solar system bodies side by side can be a bit overwhelming. For easier but fascinating visualization, two physicists have teamed up to create something that would give you a fair comparative idea of ​​the gravitational pull of our solar system bodies. The idea was to follow a bullet dropped on the bodies of the solar system from a distance of one kilometer. By comparing the speed at which they reach the surface of objects in the solar system, one could get a good idea of ​​the gravitational pull of objects. The duo produced an 88-second illustrative video that shows a bullet hitting all solar bodies while calculating its speed and elapsed time in real time.

Tweeting the video on Sunday October 3, JAXA space scientist James O’Donoghue wrote, “The gravitational forces of the solar system. Crediting his collaborator Rami Mandow, who founded an Australian community space platform called SpaceAustralia, O’Donoghue, who has been with NASA in the past, informed that the duo are using data from the planetary fact sheet from the NASA.

In the video, the Sun can be seen as the strongest pulling the ball from a distance of one kilometer in just 2.7 seconds. The second body in the solar system to win the race is Jupiter, which attracts the ball to its surface in 9.0 seconds. The third is Neptune with a score of 13.4 seconds. Saturn and Earth are fourth and fifth respectively, but their attractions are comparable, with Saturn scoring 13.8 seconds and Earth taking 14.3 seconds to attract the ball to its surface. Uranus and Venus both stand at 15 seconds while Mercury and Mars take 23.2 seconds for the ball to reach its surface. The moon takes 35.3 seconds and Pluto takes 56.7 seconds. The last is Ceres, the largest asteroid, which takes 84.3 seconds.

Please note that for the definition of “surface” scientists use an atmospheric pressure of 1 bar, since gas giant planets do not have a surface like the Earth. In addition, the calculations used surface gravity at the equators of the bodies, thus ignoring the effects of rotation for the sake of simplicity.
