of them, roughly Earth-sized) orbit pulsars and hold no chance for harboring life. Now he’s found a 4th object on the outskirts of the system,
SPACE.com is reporting. Call it a planet, call it an asteroid, Wolszczan says, but call the setup a dark, eerie twin of the inner half of our solar system. Also in the same story, news of a brown dwarf just 15 times the mass of Jupiter that has a planet-making disk of stuff around it. Together, more problems for astronomers, who still don’t have a basic
definition for the word planet or a firm idea of what separates planets from stars.”
