Wow. That is cool how you so much less on places with a lower gravitational pull.

Cool. When I went to the science center, they had a whole thing on plants. There was a part of the exhibit where you could weigh yourself. When you weighted yourself, if showed how much you would be on that certain planet. On JUPITER I weighed 197.1 that is a very,very,very big difference. Also, when I went to take my weight on NEPTUNE, my weight was 93.8. There are such big differences on your weight on different planets.

On a neutron star I weigh 9940000000000 pounds. I really am 71 pounds. It such a big difference.

I like this article.

This chart/article was really cool! I can't imagine what it would be like to weigh about a trillion pounds! You would be stuck to the ground! (Well, if there was ground on a neutron star.) I wonder how the people who invvented the scle knew to measure the gravitational pull, or if it was an accidenttal invention, like so many were. I really liked the article/chart!

Wow! The weight is a huge difference! I wonder how they can even calculate how much we would weigh on a neutron. Probably by figuring out the gravitational pull. When I went to Griffith Observatory, they had something a lot like this. There were a bunch of scales on the ground and you could see how much you weigh. If I ever went to moon (which I don't really want to) I would only weigh, 12.4 pounds! What a big difference from 74! Or if I wanted to travel to the sun (better not burn myself) I'd weigh 2,022.2 pounds! I would not like to be that heavy. I wonder what Neil Armstrong felt like when he weighed so little. It must have been odd.
Here are my weights on other places:
Mercury: 28.2
Venus: 67.7
Earth: 74.7
Mars: 28.1
Jupiter: 176.5
Saturn: 79.4
Uranus: 66.4
Neptune: 84
Pluto: 5

This is really cool article, On pluto, I weigh like 4 pounds. On Jupiter, I weigh a lot more than on pluto. The gravitational pull is very interesting. On different planets the your weight is very different. This is a very interesting article.

Sergio said...

I typed in 1 pound a calculated the amount and as it turned out, it said that there was only two planets where I would weigh more. Why did it have the moon in the planet section.

Max said...

Wow! How could they figure it out for a neutron star, the sun or a white dwarf? Nobody has actually gone there!

Caroline said...

Thats pretty cool. I've seen a lot of stuff like that before. I wonder what it feels like to way so little or so much on a different planet. You could say to someone " I way 2 pounds" and you could mean it literally, but they wouldn't know that you were talking about the moon. It is so weird that you can way almost a million pounds on a star. weight is a weird thing because if you weighed 2 pounds here, you wouldn't bounce up and down like you would if you were 2 pounds on the moon. Well, I am not sure of that because there are not many people who way 2 pounds and are able to walk. but there are animals that way less than that and they don't walk like they would on the moon.

I've learned that a different gravitational pull can change your weight, but not mass, but I had never imagined it would change it this much! In response to Max, I think that they estimated the gravitational pull of the stars based on known facts about stars closer to us. I also wonder how it would feel actually being on those planets and being so light.

Luca said...

Wow! It's cool how I only weigh four pounds on Pluto when I really weigh 60 pounds!

Kevin said...

I have also gone to the Griffith Observatory, and I think that the Observatory's approximation of your weight on different planets would be more exact than this website. However, I have never thought about this topic before, and I am sure to research this in the future.

David said...

It’s interesting to think that if I weighed myself on one of the massive gas giants, like Jupiter or Saturn, my feet would not touch solid ground. If you wanted to mathematically calculate the gravitational pull of a gas giant, it seems like it would be pretty complicated. At the center of most gas giants, there are pulpy cores that pull at matter beyond Newton’s Law of Gravity. Gas giants have an incredibly high density.

Rehaan said...

I remember going to the Griffith observatory. I had a great experience there. I can't imagine weighing 10500000000000 pounds (how much I weigh on a neutron star). I weigh 75 pounds on Earth. I am amazed by how strong the gravitational pull is on a neutron.

Jordan said...

I did a test with the number 1. The bigger the planets got, their pull gut stronger, and made you hevier. Exept for Saturn and Neptune. In the article above (free advertising) Saturn was bigger than Neptune, however you weighd more on Neptune than you did on saturn. Can someone please explain. I think it has something to do with the rings.

I did a bunch of math and research and found out that I would weigh about 8.5 pounds on Earth if it were made out of water (assuming that I could stand on water). First, I figured out the mass of the earth by researching the volume of earth and then multiplying it by the density of water (which is the same thing because it's 1). Then I converted my weight into mass by just putting 70 pounds into grams. After that I researched the radius of Earth and used the formula at the bottom of the website : Mm/r^2
David, the gas giants don't actually have a high density, they just have a huge amount of mass in them. Earth is actually more dense because it is made out of solid.

Ethan said...

I think I did something wrong. I checked over my answer and I figured out it was actually 8.5 x 10^13, but I'm pretty sure that that's not true. I'll try doing it again.

Ethan said...

This time, I know what I did wrong, I calculated the force, not the weight, and now I'm trying to calculate the weight using the force. Oh my god this is so confusing!!!

Alex M. the awesome said...

who knew i am so heavy???

chazzy Cotton said...

On a neutron star I am SUPER FAT!

Cypress said...

Wow!! I can't believe that I weigh 12040000000000 on a neutron star, and 5.7 pounds on pluto! This is really weird how the gravity can be so different on different planets. I regularly weigh 83 pounds, so I'm not that heavy

Ethan said...

I figured out that I weighed 1.170835106×10^(-9) lb on a proton.

Robert said...

Oh my gosh. A Neutron Star has such a powerful gravitational pull. A dwarf star and the Sun is also tremendous. If they're so powerful, why aren't we attracted to them? But I guess that is a going to be a really big question.
