Floating in a stream of young stars, astronomers have discovered a trinity of similar neighboring planets like Earth orbiting a very new version of our own sun.
The team discovered a young, warmer world using observations from NASA’s Transiting Exoplanet Survey Satellite.TESS), According to a new study in The Astronomical Journal. The planets are orbiting a star called TOI 451.
The system is located in a stream of newly discovered Mean-Eridanus stars, less than% of our solar system’s age, spread over one-third of the sky. These so-called rivers of stars form when the gravity of our galaxy rips apart groups of galaxies, stars and dwarf galaxies, forming an extended group that expands in flow over time.
In a statement Friday, lead researcher Elizabeth Newton said the system examines a lot of bucks for astronomers. “It is only 120 million years old and only 400 light-years away, allowing for detailed observations of these young planets. They make particularly promising targets for testing. Developed. “

Pisces-Aridans, named for the constellation, contains most of the stars, extending into a total of 14 constellations, about 1,300 light-years long.
Astronomers have determined that it is only 120 million years old – eight times smaller than previously estimated. Its youthful age makes it particularly exciting to study the formation and evolution of planets and stars.
The star of the system, TOI 451, also known as CD-38 1467, is located in Constellation Aridenus, About 400 light-years away. It contains 95% of our Sun’s mass, but is 12% smaller, slightly cooler, and emits 35% less energy.
The TOI 451 rotates every 5.1 days – five times faster than the Sun.
“The sun of the newly discovered planets is more like a teenager than our own sun. That means its planets are still changing and evolving,” Newton said.

As we know all three planets are very warm and hospitable for life, orbiting their star three times closer than Mercury which ever meets our sun. The temperature estimate is about 2,200 degrees Fahrenheit for the nearest outer planet.
The nearest planet orbits the star approximately every 2 days, while the farthest circle orbits every 16 days. They are in the size of between Earth and Neptune.
While there are over 1,000,000 known planets outside our solar system, most of them are farther from Earth than the old and newly-discovered system. According to the research team, only seven other young systems with multiple mutations have been found.
All three give astronomers a rare opportunity to study a group of rising planets. Researchers at NASA’s Hubble Space Telescope and its planned successor, The. Plans to continue studying the planets using James Webb Web Space Telescope, To examine how systems like our own solar system evolve.
“By studying these planets in terms of others, we can attach a picture of how planets form and evolve,” Newton said.
