=== Pulsar planets ===
[[Pulsar planet]]s are planets orbiting [[pulsar]]s, and [[List of exoplanets detected by timing|several]] have been discovered using [[pulsar timing]]. The radial velocity variations of the pulsar follow from the varying intervals between the arrival times of the pulses.<ref name="cornell" /> The first exoplanets were discovered this way in 1992 around the [[millisecond pulsar]] [[PSR 1257+12]].<ref>{{cite journal |last1=Wolszczan|first1=D.
