... •Pulsars emit radio waves extremely regularly as they rotate. Because the rotation of a pulsar is so regular, slight changes in the timing of its observed radio pulses can be used to track the pulsar's motion. •Like an ordinary star, a pulsar will move in its own small orbit if it has a planet.

... Have any Earthlike planets been discovered orbiting Sunlike stars? Not really. Most extrasolar planets are Jupiter-like gas giants. The planets similar in mass and size to Earth are either orbiting remnants of stars that exploded or, in the case of Gliese 581, a star much less massive and much coole ...

... In 1916, E.E. Barnard published a report of a star with the extremely large proper motion of 10.3 arcseconds per year. It is a small, red star named (appropriately) ‘Barnard’s Star’ It’s motion is large because it is only about 5.9 lightyears distant. In fact, it is moving toward us (or we’re moving ...
