NASA Confirms 5,000 Exoplanets

NASA JPL announced a cosmic milestone with the confirmed discovery of over 5,000 exoplanets (planets located outside our solar system). CNET reports: A new batch of 65 planets joined the NASA Exoplanet Archive on Monday, triggering a celebratory mood. "It's not just a number," Exoplanet Archive science lead Jessie Christiansen said in a statement. "Each one of them is a new world, a brand new planet. I get excited about every one because we don't know anything about them." The first exoplanets were confirmed in the early 1990s, which means we've set an impressive pace for discovery. NASA announced the planet count had hit 4,000 in June 2019 and it took less than three years to add another thousand to that haul. [...] We haven't definitively found an Earth clone yet, but the exoplanets spotted so far range from rocky worlds like ours to jumbo gas giants bigger than Jupiter. While 5,000 is an impressive number, it's just a tiny sliver of what's out there. Said NASA, "We do know this: Our galaxy likely holds hundreds of billions of such planets."
