Astronomers have discovered a new multiplanet system within our galactic neighborhood that lies just 10 parsecs, or about 33 light-years, from Earth.
The rocky worlds are likely not habitable, as their orbits are relatively tight, exposing the planets to temperatures that are too high to sustain liquid surface water.
