Lyzenga, a physicist at Harvey Mudd College in Claremont, Calif. The weight (or the mass) of a planet is
determined by its gravitational effect on other bodies
. Newton’s Law of Gravitation states that every bit of matter in the universe attracts every other with a gravitational force that is proportional to its mass.
How do you calculate the weight of a planet?
We calculate weight by
multiplying mass by the gravity on the surface of the planet
. So, if you know your weight on Earth and the surface gravity on Earth, you can calculate your mass. You can then calculate your weight on any other planet by using the surface gravity of that planet in the same equation.
Can u weigh a planet?
In real life,
we can’t pick up a planet and put it on a scale
. However, scientists do have ways to figure out how much a planet weighs. They can calculate how hard the planet pulls on other things. The heavier the planet, the stronger it tugs on nearby objects—like moons or visiting spacecraft.
How do you define weight on Earth?
Weight W is just another word for
the force of gravity
F g F_g
How much would a 100 pound person weigh on Mars?
If you weighed 100 lbs on Earth, you would weigh only
38 lbs
on Mars!
What is the heaviest planet?
The Latest. Fifth in line from the Sun,
Jupiter
is, by far, the largest planet in the solar system – more than twice as massive as all the other planets combined.
How much do I weight on the moon?
Your weight on the Moon is
16.5% what you would experience on Earth
. In other words, if you weighed 100 kg on Earth, you would weigh a mere 16.5 kg on the Moon. For you imperial folks, imagine you tipped the scales at 200 pounds. Your weight on the Moon would only be 33 pounds.
What weight should I be at?
| Height Weight | 5ft 1′′ (61′′) 100 to 127 lbs. 132 to 153 lbs. | 5ft 2′′ (62′′) 104 to 131 lbs. 136 to 158 lbs. | 5ft 3′′ (63′′) 107 to 135 lbs. 141 to 163 lbs. | 5ft 4′′ (64′′) 110 to 140 lbs. 145 to 169 lbs. |

Why is weight in kg?
Since there is no practical easy way to measure mass, in everyday life we use the
kilogram as a unit of weight assuming that the gravitational field is fairly constant around earth
. However scales have to be calibrated locally to compensate the slight gravitational field variation in different places.
What is the weight of Sun?
| Sun Ratio (Sun/Earth) | Mass ( 10 24 kg ) 1,988,500. 333,000. | GM (x 10 6 km 3 /s 2 ) 132,712. 333,000. | Volume (10 12 km 3 ) 1,412,000. 1,304,000. | Volumetric mean radius (km) 695,700. 109.2 |

Can you breathe on Mars?
The atmosphere on Mars is
mostly made of carbon dioxide
. It is also 100 times thinner than Earth’s atmosphere, so even if it did have a similar composition to the air here, humans would be unable to breathe it to survive.
Which is the smallest planet on Earth?
Mercury
is the smallest planet in our solar system – only slightly larger than Earth’s Moon.
What is the heaviest star in the universe?
Located in the Large Magellanic Cloud – some 160,000 light-years away – R136a1 is what’s known as a Wolf–Rayet star. Its surface temperature is over 100,000 degrees F.
Which planet has a life?
Nonetheless, Earth is the only place in the Universe known to harbor life.
