Does my physical body apply gravity to NGC 2457 and vice-versa ?

Question

sarah please change your avatar it looks evil

Answer 1

Here's NGC2457.  

http://www.skyfactory.org/deepskycatalog...

It looks like it's around 10^12 solar masses, and about 15 Mpc away.

15 Mpc = 15,000,000 x 205264 AU = 3 x 10^12 AU

So it's force on you will be

10^12 / (3 x 10^12)^2 = 10^-13 times smaller than the force from the Sun, kindly calculated by Blue Sky (above; I didn't check his work) to be 6 x 10^-3 N.

So the force between you and NGC2457 is about

6 x 10^-16 N

Answer 2

Not enough to be noticeable. Your gravity (and NGC 2457's gravity) extend on forever, but after a certain distance this amount becomes so tiny that it can't really affect anything.

Answer 3

Only if NGC2457 happens to be your license plate number and you happen to be standing on your license plate.........

Answer 4

Force of gravity = G(m1m2)/r^2

where;

G = Gravity constant

m1 = mass of object 1

m2 = mass of object 2

r = distance between them

the answer to your question is yes - go ahead and plug the values in and see what the force actually is.

To give you an example assume a person with mass 100 kg

The force of gravity with the sun is

F = 6.67428 x 10^-11 (100)(1.9891 x 10^30) / (1.496 x 10^11)^2

F = 0.0059 N (or 0.0429 pounds or 0.0027 ounces or 0.0756 grams)

Answer 5

Yes - but the distances are so large that the effect is, for all practical purposes, zero.

Almost all of the gravitational interaction between your body and anything else is with the Earth. Almost all of the remainder is with the moon and the sun. The effects of even the rest of the planets is virtually zero.

Answer 6

No, your body is not affected by anything but earth, moon and the sun. The earth, you are on it, the moon is close and big enough and the sun, cause she contains 99.99% of the mass of the whole solar system in her you are more influenced by a basketball than by Jupiter

Answer 7

There is no NGC 2457 on the NGC listing (that I can find).  Does it go by some other designation?  Do you mean NGC 2547 or some other object?

In theory,  all objects with mass affect all other objects with mass in the universe.

However, your physical body generates such a tiny gravitational field that even at a distance of a meter it isn't detectable.  So no way it can affect anything at a distance of light years.

Gravity decreases inversely as the square of the distance, so the farther an object is, the less the gravity it exerts on you.

Answer 8

Kind of.

Gravity is an attraction force between two mass, in this case, your body and NGC 2457.

The formula for the gravitational attraction in this case (in Newtons) is:

the universal gravitational constant (6.674 * 10^(-11) times the (mass of NGC 2547) times the (mass of your body) divided by the (distance in meters between you and NGC 2547) squared

This force will be an attraction force exerted between you and NGC 2547

It will be an extremely small, unmeasurable force since the distance is so large, but it is a force.

miaow

Answer 10

If your physical body and NGC 2457 are both objects with a mass greater than infinitesimal and a distance between each other smaller than infinite, then yes there is a gravitational force between you.
