If the Pyramid of Cheops was on Pluto, then an ordinary baseball could be easily thrown over it .
Astronomer James O'Donoghue of the Japan Aerospace Exploration Agency created a special illustrative video to show how a baseball would behave on other planets in the solar system, as well as on Pluto and the Moon. That is, how high and far this ball can fly in other worlds, writes ScienceAlert.

Throwing an ordinary ball on Earth is easy enough, although it can not fly very far. As for the baseball, it can fly much farther, because it is smaller. But what happens if you throw a baseball on the moon, for example?
To get an idea of the strength of gravity on our satellite, you can watch a video with the astronauts of the Apollo mission, who moved on the surface of the moon. But you can more clearly understand the behavior of objects on our satellite using the following statement by O'Donoghue: if you throw a baseball on our satellite, then it could easily fly over the Leaning Tower of Pisa (if it were there), which is 57 meters high.< /p>
By the way, Focus already wrote that the Leaning Tower of Pisa was able to rise by 4 centimeters.
It's a little more difficult to imagine the effect of gravity on Saturn, because no one has been there yet, and even more so no one has filmed a video on this planet. But astronomer James O'Donoghue has created a video that shows the flight of a ball on every planet in the solar system, as well as on Pluto and the Moon.
According to the scientist, we can only judge what is happening on other planets with using images and videos (only from the Moon and Mars). Therefore, his work is intended to understand how gravity works in other worlds.
The scientist for his calculations used data on how much force and maximum speed an average adult can throw a baseball. And then he added the known values of gravity on different worlds, which determine the flight of this object.
It is the force of gravity on different planets of the solar system, as well as on the Moon and Pluto, that determines how high and far the ball can fly. The force of gravity of any space object depends on its mass. The greater the mass of the planet, the stronger its force of attraction, but the density of the planet also plays an important role.
“For example, the mass of Saturn is 95 times the mass of the Earth, but this is the least dense planet in the solar system. Therefore, the force of gravity here will be less than on Earth,” says O'Donoghue.
Therefore, if you throw the ball on Saturn, it will fly almost the same as on Earth. But on Pluto, which was once considered a planet and has now moved into the status of a dwarf planet, the throw of the ball will be really impressive.
Pluto is a third smaller in diameter than the Moon and it has such weak gravity, that is, a thrown baseball could easily fly over the largest Egyptian pyramid, the Pyramid of Cheops (139 meters high), and it would fly very far, about 16 times farther than on Earth.
“I even thought about how boring it would be to trip while running on the surface of Pluto,” says O'Donoghue.
Focus< /em> already wrote that scientists were able to solve one of the mysteries of Pluto's moon Charon, which changes the perception of the dwarf planet itself.
In detail about the main features of Pluto and why this dwarf planet intrigued scientists, Focus already wrote.
As for the Moon, then to As Focus already wrote, NASA is actively preparing for the re-landing of astronauts on our satellite. So far, only the first stage of the new Artemis lunar program has been successfully completed on the way to this task.
