The time it takes to complete one orbit varies depending on the object and its orbital path. For example, the International Space Station orbits Earth approximately every 90 minutes, while Mars takes about 687 Earth days to complete one orbit around the Sun.

This is Kepler's Third Law of Planetary Motion. Let's assume the orbit is circular. The law is: The time to orbit the Sun, squared, is proportional to the distance from the Sun, cubed. Really the orbits are ellipses and we need to use the "semi-major axis" of the ellipse instead of simply the distance from the Sun.
The moon is in constant orbit around the earth, all the time.
Planet Neptune takes the most time to orbit the sun, as it is the farthest away.

There are many American past-times, most of which include sports. There are many debates over if baseball or football is the best, but baseball has been called "The Great American Past-Time" for many years.
See what you orbit around the earth in different orbits around the time required to transfer different. Check the link.
you need to have the eye of truth
It needs to change its velocity, which of course it does. I know you realize this, but keep in mind that the planet doesn't 'need' to sweep out equal areas of its orbital plane in equal amounts of time. It's a characteristic of elliptical orbits.

Yes, it does. You can tell by putting a period in the spot where you think the semicolon should go and see if it makes sense. For example: He was hungry it was hours past lunch time. He was hungry. It was hours past lunch time. He was hungry; it was hours past lunch time.
A time machine. And probably a lot of guns!
