Mass.\n\nStuff which weighs a lot sucks other stuff towards it.\n\nIt's the sun's mass which keeps the Earth from flying off in a straight line into space.\n\nAnd it's the Earth's mass which pulls us towards its centre.

Fussion in the sun is caused by massive gravity well within the sun.  So where is gravity the greatest the center The Center the center   The fussion causes a really big explosion that sends out charage ions flying through space space space space Space in the way of radiation waves.  Interesting eh?

I'm sure that information is available on one of the NASA sites, I don't have time to look for it right now.  The gravity of Jupiter has been approximated as 2.5 times the gravity of Earth, but the mass of Jupiter is almost 318 times that of the Earth.  For some reason, I was under the impression that mass and gravity were a direct proportion.  I just found that I was wrong today.  Thanks for asking your question; I just became even smarter that I was.

Earth is revolving in orbit, held in place by the Sun's gravitational pull

Every mass in the universe attracts every other mass in the universe. The force of the attraction between any two objects is proportional to their two masses and inversely proportional to the square of the distance between them.\n\nThe formula for the force is F = G x m_1 x m_2 / r^2 where \n\nG  = 6.6742 × 10^( −11) N m^2 / kg^2    is the gravitational constant.\n\nThe gravitation that you feel is from the attaraction between the mass of the earth and the mass of your body.\n\nGravity is not caused by the the earth's magnetic field, its rotation  on  its axis, or its revolving around the sun.

The sun is made of hydrogen.

A real good question, but one that I've never seen any kind of discussion about. It would be close to impossible to determine our Sun's galactic orbit because there are just too many variables involved that would periodically change the orbit--gravitational disturbances by other stars, galaxies, and varying densities as we traverse the spiral arms, etc.,. Also, it takes our Sun some 250-million years to make one complete orbit and we haven't been around long enough to get any kind of reliable idea of current orbital parameters.

Yeah, gravity.  That's what slings everything around.  The enormous mass of the sun gives it an incredible gravitational pull.

The sun is spherical for the same reason most large astronomical bodies are spherical - gravity. \n\nGravity will pull equally on all parts of a body, so every part of it will try to get as close to the center as possible.  As astronomical bodies form and coalesce, they move closer to the center until the opposing pressure (for example, from being solid like the earth, or the pressure of nuclear radiation as is found in the sun) equals the force of gravity.  Since every part of the sun is trying to collapse in equally, every part of the sun's (earth's, other planets', other stars') becomes equidistant from the center.  Which is the definition of a sphere!\n\nNote that not all astronomical bodies are perfect spheres, though!  Small objects - say, like the moons of Mars - don't have enough gravity to pull themselves into a spherical shape.  And some bodies have other forces coming into play.  For example, Jupiter is spinning so fast (once every 10 hours) that it bulgest out 4,300 km at it's equator due to centrifugal force.  This happens with the earth, too - the earth is 22 km fatter at its equator due to centrifugal force.

Weight is a force, but when something is weighed you actually measure it's mass assuming you are in an environment in which the force of gravity is constant (i.e., you're at a fixed location <radius from the center> on a planet or massive planetary mass).\n\nof course, one's mass can be approximated by W=mg at fixed radii from such planetary masses (like the earth, a massive asteroid, a superdense star, whatever...) if the force of gravity, g, is known at that radius.\n\nThere are 2 possible variables here - mass and the force of gravity.  Which one do you know?  usually an approximation for g is given.  Which one do you measure, then...that would be mass.

Gravity is a form of kinetic energy.  The sum of the vectors for any gravitational system is always zero.  So, energy is neither created or destroyed.\n\nBTW.  Mass also has to be taken into account.  The destruction of mass in the sun is what created the radiant energy the composes sunshine.

The sun is by far the largest object in our solar system. It contains 98% of the solar system's total mass.\n\nIt would take 109 earths to stretch across the sun, and it would take over one million earths to "fill up" the sun if it were hollow.\n\nIf you think of the sun as being the size of a basketball, then the earth would be about the size of the head of a pin.\n\nThe diameter of the Sun is 865,400 mi \nEarth equatorial diameter=7926 mi (12760 km)\nEarth polar diameter=7900 mi (12720 km)\n\nSun's surface area is approximately 12,000 times that of Earth.\n\nMore info:
