Planets revolve on their axis. Separate to this motion, they also orbit the Sun. The force of gravity and the momentum of the objects keep them going.

The inner, or Terrestrial planets are very small in comparison to the outer, or Jovian planets. The smallest Jovian planet, Uranus, is 14.5 times larger than the largest Terrestrial planet, Earth.
Any people in and around the track that is in the related links list.
It is not gravity because there is no gravity in space, only some on certain planets, deffiantly on earth. It is done by the strength from other planets the sun for instance. Heat waves. Some of the gravity in space does help keep the planets and satellites in orbit.
For a standard track (1/4 mile length), 17.4 laps equals 7 km (7 km = 4.35 miles = 17.4 laps)
As far as I can imagine, No. Astronauts and space shuttles are tiny with respect to the planets. Mostly,space shuttles are in between two orbits. To observe planets revolving around the sun, you need to be very far away (so that you can see this view. Think of this: If you are standing in the middle of the track of a gigantic circular race track,would you be able to see all the cars moving around the race track? No. You would just be able to see the cars zooming in front of you. And it would appear as though the cars are moving straight. You would only be able to see all the cars moving round the enormous track if you were on a helicopter, or sitting on a seat high above the track. This is exactly the same thing with the planets. You can't see them all revolve unless you are really far away.And, astronauts don't go that far out.
For anything beyond 100 metres, a running track will need to go around a curve. The measurement of the track length along the curve requires knowledge of geometry.
the movements of the Sun, Moon, planets and stars.
The planets constantly move through the constellations and other patterns of stars, always staying pretty close to the same track. Sadly, their track never comes anywhere very close to Orion.
Vuelta has many possible meanings depending on exact usage: Return, Turn (on a road, rail, river), Turn around (something), Turn over, Flip around/over, Revolve, Spin, Lap (around a track), Detour (take a detour around an obstruction), Walk (Taking a walk [around the block], walk as a pastime.)
Exo planets
You run around on a big track!
When the Greeks started it along with the Olympics.
Gravity.
Yes, if it is a circular track.
Both new planets and stars are being formed. Scientists are actually watching the formation of planets and keeping track of which ones would be able to support life.
If you are saying that the track is .125 of a mile, then it would be a 200 meter track. In that case, eight laps around the track would be a mile.
