Exoplanets, or extra-solar planets, are those planets which revolve around stars other than our Sun. A large number of Exoplanets have been detected and many more are continually added to the list.
Not necessarily. If she is too available then she has to make sure that she doesn't come off as desperate otherwise a guy may see it a sort of a chore to talk to her and may try to avoid it because he knows that if he starts talking to her then she won't stop because she's "too available".

The length of a year for a planet is defined as the time it takes for that planet to orbit its star.

Exoplanets are located in other solar systems. They are planets that have been detected orbiting other stars, by causing the star (or their sun) to 'wobble' as the bodies exert their gravitational pull on each other.

Well, there is a technique called the 'Wobble' Technique. Theoretically, when a planet is rotating around a star, the star is slightly 'wobbled' around due to the gravitational force of the exoplanet. Scientists search for 'wobbling' stars and find exoplanets in this way. Another technique is the go…
