In an animation, Mars, Earth, Venus, and Mercury orbit the sun. Text, April 5, 2022. 5,000 Strange New Worlds
Thirty years ago, the only planets in the known universe were in our own solar system.
The first discovery of planets orbiting a star other than the Sun was made in 1992.
An avalanche of exoplanet discovery and confirmation followed – led by NASA's Kepler Space Telescope – and reached 5,000 in March 2022.
A Hubble Space Telescope image depicts blocked starlight next to Exoplanet PDS 70b. Text, Today it is estimated that most stars host at least one planet.
Many planets have been discovered that are types not found in our solar system, like hot Jupiters and super-Earths.
Planets have been discovered orbiting double star systems, and even collapsed "dead" stars.
Our own solar system, stretching more than 4 billion miles, has come to feel like a local neighborhood...
In an animation, two black orbs orbit the Sun. Circles radiate outside the Kepler Field.
...while the universe proves once again to be full of more possibilities than we can imagine.
