How We Search. Exoplanets, or planets in solar systems other than our own, sometimes orbit directly between the Earth and their host star.When the planet orbits in front of its star, it blocks a small amount of light. CfA scientists use the Transiting Exoplanet Survey Satellite (TESS) and the Kepler space telescopes as well as the ground-based robotic telescopes of the MEarth project
Exoplanet Facts
Exoplanets also known as extrasolar planets, are planets which exist outside our solar system. There have been over 4,000 confirmed discoveries of exoplanets. In 1992 two planets orbiting a distant pulsar became the first exoplanets to be detected. In 1995 51 Pegasi B was the first exoplanet to be discovered orbiting a sun like star.

The Nine Planets Asteroids are small, rocky, debris leftover from the formation of our solar system around 4.6 billion years ago. There are currently over 822,000 known asteroids.
Finding Life Beyond Earth is Within Reach
The Kepler observations have led to estimates of billions of planets in our galaxy, and shown that most planets within one astronomical unit are less than three times the diameter of Earth. Kepler also found the first Earth-size planet to orbit in the "habitable zone" of a star, the region where liquid water can pool on the surface.
Solar System Facts
Our solar system includes the Sun, eight planets, five dwarf planets, and hundreds of moons, asteroids, and comets. but its existence is predicted based on mathematical models and observations of comets that likely originate there. The Oort Cloud is made of icy pieces of space debris - some bigger than mountains – orbiting our Sun as far
NASA''s Webb Confirms Its First Exoplanet
"There is no question that the planet is there. Webb''s pristine data validate it," said Lustig-Yaeger. "The fact that it is also a small, rocky planet is impressive for the observatory," Stevenson added. "Webb is bringing us closer and closer to a new understanding of Earth-like worlds outside our solar system, and the mission
Other Worlds
In addition to studying planets outside our solar system, scientists want to learn more about our own home. Webb will be powerful enough to identify and characterize comets and other icy bodies in the outermost reaches of our solar system (like objects in the Kuiper Belt and comets), which might contain clues to our origins on Earth.

But a new raft of discoveries marks a scientific high point: More than 5,000 planets are now confirmed to exist beyond our solar system. Astronomers have now confirmed more than 5,000 exoplanets – planets beyond our solar system.
The nearest potentially habitable planet to Earth – Exoplanet
UNSW Australia astronomers have discovered the closest potentially habitable planet found outside our solar system so far, orbiting a star just 14 light-years away. "The close proximity of the planets around Wolf 1061 means there is a good chance these planets may pass across the face of the star. If they do, then it may be possible to
Solar System
The Solar System [d] is the gravitationally bound system of the Sun and the objects that orbit it. [11] It formed about 4.6 billion years ago when a dense region of a molecular cloud collapsed, forming the Sun and a protoplanetary disc.The Sun is a typical star that maintains a balanced equilibrium by the fusion of hydrogen into helium at its core, releasing this energy from its
Finding Distant Worlds | News | Astrobiology
We know that there are at least 75 planets outside our own solar system, orbiting their distant stars. The rate of planet discovery has sped up recently, and many more planets will likely be discovered in the weeks and years to come. And yet, we have never seen any of these planets with our own eyes.
NASA Is Taking a New Look at Searching for Life Beyond Earth
Beyond our solar system, missions, such as Kepler and TESS, are revealing thousands of planets orbiting other stars. A zoom into the Hubble Space Telescope photograph of an enormous, balloon-like bubble being blown into space by a super-hot, massive star.

6 FAQs about [Are there planets outside our solar system]
Do all stars have exoplanets?
Most stars in our galaxy have at least one exoplanet, and many are unlike any of the worlds in the Solar System. Some exoplanets could be habitable and are prime targets in the search for life beyond Earth. What are exoplanets? An exoplanet, short for “extrasolar planet,” is any planet that isn’t in the Solar System.
Are exoplanets different from the Solar System?
One thing that has become abundantly clear in humanity's exploration of exoplanets is that planets come in a much wider range of categories than can be seen in the solar system.
Can astronomers find exoplanets?
Because planets in other solar systems are extraordinarily difficult to see directly, astronomers have had to come up with innovative ways to hunt for them. Only recently have our technology and techniques been up to the task of finding exoplanets. Telescopes on the ground and in space have uncovered thousands of planets beyond our solar system.
Are exoplanets habitable?
Exoplanets that orbit in the so-called habitable zone — the region around their star where it's not too hot or too cold to sustain liquid water — are targets for the search for life outside the solar system. Can life survive on exoplanets? That depends on the exoplanet.
How many exoplanets are in the Solar System?
There are 7,026 known exoplanets, or planets outside the Solar System that orbit a star, as of July 24, 2024; only a small fraction of these are located in the vicinity of the Solar System. [ 3 ]
How many planets are there beyond our Solar System?
