Welcome back. How many stars are there in our own galaxy, the Milky Way? A number frequently bandied about is billion. This is a nice round number. The number could be as high as billion; also a nice round number. In an interesting coincidence, the number of galaxies is estimated at billion, a number that will no doubt increase as we peer into the farthest recesses of the universe. So, a billion galaxies, and in each billion stars — the numbers are getting out of hand even for a geologist who works in millions of years.
So when astronomers announce that there are probably more exoplanets than stars in our own galaxy ergo all the other galaxies , our ego-centric view of the universe seems just plain silly. As of September 25, , there were confirmed planets , NASA candidates, and solar systems. The NASA plot shows the estimated planet size and orbital periods, relative to Earth; the majority of exoplanets apparently whiz round their stars in less than days, some in a few hours.
Having a decent telescope at your disposal is a good start. Land-based telescopes are okay, but the real successes have been with orbiting, satellite-based telescopes.

Kepler was launched by NASA in March and was tasked with watching a swath of sky containing about , sun-like stars. The second orbiting observatory, TESS Transiting Exoplanet Survey Satellite , launched April 18, , is also dedicated to finding exoplanets, and in its first few days of operation has made some exciting discoveries. Kepler and TESS use a method of detection called Transiting — several other methods have been used but the transit method has been the most successful e.
An observer will see velocity changing as the star move towards and away from Earth. A nice summary of detection methods has been compiled by The Planetary Society.
