Earth's Twin Sister Found: 'HD 137010 b' Orbits Star in 355 Days
- •Scientists discovered 'HD 137010 b', a planet 146 light-years away, similar in size to Earth and conditions to Mars.
- •The planet completes an orbit around its sun-like star in 355 days, closely matching Earth's year.
- •There's a 50% chance it lies within its star's 'habitable zone', despite potential surface temperatures of -70 degrees Celsius, suggesting a 'super snowball' world.
- •The discovery was initiated by 'citizen scientists' through the 'Planet Hunters' project, with initial signals detected by then-high school student Dr. Alexander Wanner.
- •HD 137010 b is closer and brighter than previous Earth-like discoveries, allowing for more in-depth research with next-generation telescopes.
Why It Matters: Scientists have discovered 'HD 137010 b', an Earth-sized planet with a 355-day orbit, offering new hope for life beyond Earth.
