Of the more than 300 other known exoplanets, all have been detected indirectly by their effects on their parent stars — either a wobble in induced by the object's orbit or a decrease in detected light from the star as the planet passes in front of it.

For example, as Kepler has spotted 1,235 exoplanet candidates so far - 53 of which orbit stars in their habitable zones - knowing approximately how many stars there are in our galaxy (there are thought to be around 300 billion stars in the Milky Way), an estimate can be made of how many worlds are orbiting these stars.

A large number of exoplanets and planet candidates are known, but the Earth - size exoplanets in Earth - like orbits still reside in an open part of discovery space.

Before Wednesday's Kepler announcement, we knew of just over 500 exoplanets orbiting stars in the Milky Way.

All we know is how long the exoplanets take to orbit the star and their physical size.

This exoplanet, known as Kepler - 78b, orbits its star very closely every 8.5 hours, making it much too hot to support life.

Needless to say, all this talk of «Earth - sized» worlds (and the much - hyped «Earth - like» misnomer) has added fuel to the extraterrestrial life question: If there's a preponderance of small exoplanets - some of which orbit within the «sweet - spot» of the habitable zones of their parent stars - could life as we know it (or Earth - Brand ™ Life as I like to call it) also be thriving there?

The space telescope will observe stars in our cosmic neighbourhood that are known to be orbited by exoplanets.

KELT - 3b is the third transiting exoplanet discovered by the KELT survey, and is orbiting one of the 20 brightest known transiting planet host stars, making it a promising candidate for detailed characterization studies.

Since Earth is the only planet known to play host to life, Sun - like stars and their exoplanets are considered promising targets in the search for E.T.. However, simply discovering a rocky Earth - sized world orbiting a Sun - like star does not guarantee the existence of life.

One of the prime targets for observation are nearby Earth - size worlds such as TRAPPIST - 1d, and the closest known exoplanet to Earth, Proxima b, which orbits its star a mere 4.25 light - years away.

Over at least two years, TESS will survey more than 200,000 stars, and will be able to find many new exoplanets orbiting these stars, including Earth - sized and super-Earth-sized (larger than Earth but smaller than Neptune), which are now known to be the most common in our galaxy.

Until confirmation, these transits are known as «candidates,» and on June 19, NASA announced the detection of 219 candidate exoplanets, 10 of which are Earth - sized worlds orbiting within their stars» habitable zones.

If this is true, then that means that we don't know what kind of orbit an Alpha Cen exoplanet would have.

The diversity of masses, sizes and orbits of known exoplanets has prompted recent efforts in the scientific community to explore the broad range of interactions that can exist between planets and their host stars.

Whilst all the exoplanets discovered around the red dwarf, known as TRAPPIST - 1, are capable of hosting liquid water on their surfaces, three are in orbit in what is known as a star's habitable zone, making them an attractive prospect for scientists searching for life outside of our solar system.

The nearest known exoplanet — orbiting the star Proxima Centauri — is only 4.2 light - years away.
