1). As an artificial space vehicle approaches and passes another planet, we can observe the effect of the other planet on its motion. 2). Knowing the vehicle's mass, and the effect the other planet has on its motion, we can calculate the other planet's mass.
3). Knowing the time the other planet takes to revolve around the sun, we can calculate its distance from the sun.
4). Knowing the other planet's distance from the sun, and its apparent size as seen from earth, we can calculate its actual size.
5). Knowing the other planet's actual size and mass, we can calculate the gravitational field at its surface, or at any distance from its center.
6). Knowing the gravitational field at any distance from the center of the other planet, we can calculate the weight that any familiar object would have if it were on or near that planet.
To calculate weight on other planets, you can use the formula: Weight Mass x Gravity. The mass of an object remains the same, but the gravity on different planets varies. You can find the gravity of a planet by looking it up online or using a formula. Then, multiply the mass of the object by the gravity of the planet to find the weight on that planet.
To find your weight on other planets, you would multiply your weight on Earth by the planet's surface gravity relative to Earth's surface gravity. For example, your weight on Mars would be your weight on Earth multiplied by 0.38, as Mars' surface gravity is 0.38 times that of Earth.
As Terry Pratchett noted, speciesism is more interesting than racism.
Considering water is made with Oxygen and Hydrogen, the only planets that could have water on them would have to have plants. Humans haven't discovered many planets due to the difficulty. We are not advanced enough to know much of this. As space exploration goes on, people learn knew things about the Universe and planets. If humans ever did find a planet with wildlife on it, we'd probably land there, and manage to survive. Humans would most likely eventually colonize on other planets. However, the chances of planets in our solar system having wildlife on them is slim, and to find these, we'd need to travel very far from Earth, once again bringing my point that humans are not advanced enough.
scientists can't really find if there is life on other planets
ya,ofcourse from my view
The basic requirements of human beings are air and water, if these two things are present on any planet, then it can be possible to live on that, but unfortunately our astronomers did not able to find any of such planet, but in future it can be possible. So hope for the best!
It is possible, even likely, that there are other planets that could support life. We have yet to find any.
Mostly to study other planets and to find out about our solar system. They are used to take pictures of planets as well.
Hundreds of billions of stars, some of them with planets.
People want to explore other planets to expand our understanding of the universe, to discover if life exists beyond Earth, and to potentially find resources that could benefit humanity in the future. Exploration of other planets also allows us to push the boundaries of science and technology.
The Greeks did not 'find' five planets. The Earth and theother five visible planets have been visible on any clear night for as long as humans have walked the Earth. They were known to any caveman with normal vision, a touch of insomnia, and enough brain cells to be interested in the things he saw in the sky.
