On Mercury, a 100-pound individual would weigh 37.8 pounds. It's a challenging one since there's no genuine surface to stand on. Saturn's gravity is equivalent to that of the Earth at the equator, thus if you could weigh someone, they would weigh roughly the same. The Moon's gravity is about 1/6th that of Earth, so it would only account for about 5% of your weight if standing on it.
The closest planet to Mercury is Venus, and the distance between them is about 4.5 billion miles. Because of this, the gravitational pull of Venus is not enough to account for all of Mercury's weight; otherwise, we would see evidence of this in the form of different levels of attraction on each planet. Instead, we must look further afield for the source of Mercury's burden.
Our next stop should be Alpha Centauri, a binary star system about 24 light years from Earth. If one component was replaced by a mass similar to that of Mars, then the combined gravity of these stars would be capable of accounting for all of Mercury's weight.
In conclusion, Mercury is deflected away from the Sun by the Earth's gravity. This means that it never gets completely out of orbit around the Earth, and so it always stays within our magnetic field.
Because Mercury has less mass than Earth, its surface gravity is lower than Earth's. Mercury's surface gravity is only roughly 38% that of Earth's, therefore if you weigh 100 pounds on Earth, you would only weigh 38 pounds on Mercury. A person's weight on Mercury would be measured in kilograms (kg).
The reason why people who go to Mercury want to lose weight is because without artificial aid, humans will naturally lose weight when they don't eat any more than what they need for energy and other basic requirements. So if you are on a diet to lose weight, you should try to limit yourself to 2,200 kilojoules (kJ) of energy per day - about 500 calories - plus whatever amount of water is needed to keep your body hydrated. This is well below the average daily energy requirement of about 2,800 kJ reported by scientists for adults working outside laboratories under normal conditions. The only way to increase this requirement is by using more energy above what is needed for basic functions like breathing and sleeping.
On Mercury, due to its low surface temperature, people would need to wear warm clothes and boots to not lose heat energy. Also, they would need to carry enough food with them to last until they reach a place where there is an atmosphere and where it is possible to find something to eat. Otherwise, they would eventually die from starvation or heat exhaustion.
If you weigh 100 pounds on Earth, you would only weigh 38 pounds on Mercury. Because Mercury weighs less than Earth, its gravity would exert less force on your body. If you were on Jupiter, though, you would weigh a massive 253 pounds! On Jupiter, 1 pound equals 454.6 grams. So, to weigh 100 pounds on Jupiter, you would have to weigh 44,000 grams (or about 500 pounds).
The conversion from pounds to kilograms is easy. Just divide the original weight in pounds by 2.204622. Then, multiply that number by 0.453516 to get the equivalent amount in kilograms.
So, if you weighed 100 pounds and then converted it to kilograms, you would get 220.7 grams. That's more than 10% over the maximum allowed weight for astronauts! To put this in perspective, an average person who weighs around 150 pounds will already be carrying about 50% more weight than the limit for astronauts. An athlete or a person with large bones could possibly carry more than that.
Astronauts are also required to be in good physical condition before being accepted into the program. So, even if an astronaut was extremely obese, they might still not be able to join the program because of health concerns.
The final factor that can affect how much an astronaut can weight is their age.
To calculate the weight of Mercury, divide the weight on Earth by the earth's gravitational force, which is 9.81m/s2. This determines the object's mass. As a result, an object or person on Mercury would weigh 37.72 percent of what it would weigh on Earth. As a result, a human on Mercury would be lighter than on Earth. The average human weighs about 60kg (132lb), so a person on Mercury would weigh around 18.6 pounds.
The closest approach Mercury makes to the Sun is when it passes behind the Sun from our perspective on Earth. Because of this, only parts of Mercury can be seen from Earth. Only four of the seven planets are visible from Earth with the naked eye, because the others lie beyond the Moon. However, all seven have been photographed by astronomers using telescopes from across the world.
It's not easy being green! Venus and Mars both used to be able to live in conditions on their surfaces that would have killed any other organism. But over time they lost most of their atmosphere and were unable to block out the heat from the sun. So they turned into deserts. Today they're very hot places to live.
Where is Jupiter located? Jupiter is one of the four major planets located between Mars and Saturn. It has two small moons, Ganymede and Europa, that are larger than many planets.
How does Jupiter look? Like a giant ball of gas.
