Now, astronomers know that planets orbit the two closest star systems to our solar system. Barnard’s Star has served as a kind of white whale for astronomers over the decades as they have tried ...

The planets form a tightly packed, close-in system, having short orbital periods of between two and seven Earth days (for comparison, our sun's closest planet, Mercury, orbits in 88 days).

The two exoplanets, or planets outside of our solar system, orbit a star called TOI-1453, which is slightly cooler and smaller than our sun. Located about 250 light-years from Earth in the Draco ...

Based on the progress made so far, some experts think we’ll find the first truly Earthlike planets in the next year or two. By combining information from radial velocity and transit methods ...

And the two remaining planets, Uranus and Neptune, could be sighted only by observers with good binoculars or a backyard telescope. Plus, they needed to know exactly where in the sky to look.
