How many exoplanets are there?
On March 21, 2022, the number of known exoplanets passed 5,000 according to the NASA Exoplanet Archive. This 360-degree animation and sonification tracks humanity’s discovery of the planets beyond our solar system over time.

How many exoplanets have we discovered?
The count of confirmed exoplanets just ticked past the 5,000 mark, representing a 30-year journey of discovery led by NASA space telescopes. Not so long ago, we lived in a universe with only a small number of known planets, all of them orbiting our Sun.
are exoplanets habitable
What are the characteristics of a habitable exoplanet?
The main feature of potentially habitable exoplanets is that they have to be located in the habitable zone of their stellar systems (although life is also possible outside this zone, and estimates of the extent of the zone can also vary widely).
What is the conservative habitable zone for exoplanets?
List of exoplanets in the conservative habitable zone. In astronomy and astrobiology, the circumstellar habitable zone (CHZ), or simply the habitable zone, is the range of orbits around a star within which a planetary surface can support liquid water given sufficient atmospheric pressure.
What are the habitable planets?
Some of the planets discovered by Kepler are rocky planets that are at a very special distance from their star. This sweet spot is called the habitable zone, where life might be possible. Artist’s rendition of the Kepler spacecraft.
What do we know about exoplanets from NASA?
In 2009, NASA launched a spacecraft called Kepler to look for exoplanets. Kepler looked for planets in a wide range of sizes and orbits. And these planets orbited around stars that varied in size and temperature. Some of the planets discovered by Kepler are rocky planets that are at a very special distance from their star.
nasa exoplanets map
What is the first ever map of an exoplanet?
This is the first-ever map of the surface of an exoplanet, or a planet beyond our solar system. The map, which shows temperature variations across the cloudy tops of a gas giant called HD 189733b, is made from infrared data taken by NASA’s Spitzer Space Telescope.
What is the farthest away from Earth are the exoplanets?
The farthest lies in the center of our galaxy, 25,000 light-years away. Most of the known exoplanets, numbering in the thousands, have been discovered by NASA’s Kepler space telescope, which uses a different strategy called the transit method. Kepler’s cone-shaped field of view is shown in pink/orange.
nasa exoplanets catalog
What is the Habitable Exoplanets Catalog?
New from the Planetary Habitability Laboratory at the University of Puerto Rico, Arecibo, the Habitable Exoplanets Catalog is an online database for scientists, educators, and the general public focused on potential habitable exoplanet discoveries.
What is the exoplanet Encyclopedia?
This continuously updated exoplanetary encyclopedia combines interactive visualizations with detailed data on all known exoplanets. Click on a planet’s name to see 3D model of each planet and system along with vital statistics.
