Question

What are Celestial bodies that have gigantic orbits?

Answer 1

ALL the celestial bodies have gigantic orbits--some are just a little more gigantic than others.

Even our closest celetial neighbor, the moon, has an orbit so big, and it is so far away (250,000 miles--by comparison, the earth is only 7000 miles in diameter), that, if you could shoot a laser at it, the light from the laser, travelling at 187,000 miles per SECOND, would take about a second and a half to reach the moon.  Like the lag when you are talking on a cell phone to a friend right beside you.  You say something, and a second later, you hear it come out of your friend's cell phone.

The planets have even more gigantic orbits.  I think Pluto takes over 200 years just to go around the sun once, the same as our 1 year.

And remember, the sun is orbiting the Milky Way galaxy, somewhere out in one of the spiral arms.  The Milky Way is about 10,000 light YEARS across, meaning if you could go as fast as light, like a star ship, it would still take you 10,000 years to get from one side of the galaxy to the other.  So, depending on how far out the Sun is from the center of the galaxy, it's orbit might be 5,000 or 10,000 light YEARS across.  A light year is how far light can travel in one second.  If it can go 186,000 miles in one SECOND, you can imagine how far it can go in a year.  Somebody has calculated how long it will take for the sun to go around the galaxy one time, but I can't remember how long it is.  Since the sun, last I heard, is only going about 55,000 miles per hour, (about 1/10,000 as fast as light), and it would take LIGHT over 30,000 years to orbit the galaxy out near the edge, one orbit for our sun will take 10,000 times longer than for light to make the trip.
