How many undiscovered exoplanets are there?
To date, more than 4,000 exoplanets have been discovered and are considered “confirmed.” However, there are thousands of other “candidate” exoplanet detections that require further observations in order to say for sure whether or not the exoplanet is real.
How many exoplanets did Kepler discover?
2,662 exoplanets
Kepler observed 530,506 stars and discovered 2,662 exoplanets over its lifetime.
Did Kepler discover exoplanets?
By the end of its mission, Kepler had discovered 2,662 extrasolar planets, about two-thirds of all planets then known. One of these, Kepler-22b, has a radius 2.4 times that of Earth and was the first planet found within the habitable zone of a star like the Sun.
Who discovered first exoplanet?
Aleksander Wolszczan
On 9 January 1992, radio astronomers Aleksander Wolszczan and Dale Frail announced the discovery of two planets orbiting the pulsar PSR 1257+12. This discovery was confirmed, and is generally considered to be the first definitive detection of exoplanets.

When was the first exoplanet discovered?
1992
The first exoplanet discovered was in 1992 and, since then, most exoplanets found have been less than 3,000 light-years from Earth. But M51-ULS-1b, orbiting 28 million light-years away, would be the first exoplanet ever found in another galaxy.

Where can I find all the new exoplanets?
With the touch of a screen or the click of a mouse, you can visit the newly discovered TRAPPIST-1 system in the our exoplanet atlas. The New Worlds Atlas contains every exoplanet discovery, powered by NASA’s Exoplanet Archive, the official database used by professional astronomers engaged in exploring new worlds.
When was the first exoplanet discovered outside our Solar System?
In 1992, astronomers discovered the first exoplanet, or planet outside our solar system. But it didn’t come in any form they’d really anticipated. The first exoplanets ever discovered were found orbiting the pulsar PSR B1257+12. It took years for astronomers to find exoplanets around sun-like stars.
Who is the Chief Scientist for the NASA Exoplanet Program?
If you put the question to Karl Stapelfeldt, chief scientist for NASA’s Exoplanet Exploration Program, he’ll simply run down the list of exoplanet detection methods that require intimate knowledge of the host star:
Where did scientists find water fingerprints on exoplanet?
Scientists used NASA’s Hubble and Spitzer space telescopes to find water “fingerprints” in the atmosphere of a hot, bloated, Saturn-mass exoplanet some 700 light-years away.
