"Scientists have discovered a pulsar (with an estimated mass of between 1.4 and 2 solar masses) traveling at an estimated 2.5 to 5 million mph (0.0035c to 0.007c). According to NASA's Chandra X-ray Observatory:
Originally discovered with the European Space Agency satellite INTEGRAL, the pulsar is located about 60 light-years away from the center of the supernova remnant SNR MSH 11-61A in the constellation of Carina. Its implied speed is between 2.5 million and 5 million mph, making it one of the fastest pulsars ever observed.
By comparison, one of the fastest man-made objects is the Voyager-1 spacecraft, currently traveling at an estimated 38,100 mph relative to the sun, or approximately 0.000056c (5.6 x 10-5 c)."

I checked the WP link you've got there by the way, and did conversions myself. You do very odd mixing of commas and periods, and find that the Milky Way's speed relative to the CMB is 552 km/s or 1,230,000 mph (using the proper number of significant figures). The pulsar's speed is quoted as 2.5 to 5 million mph, or at least double and up to nearly five times faster than the Milky Way's speed relative to the CMB. The pulsar is moving away from its supernova remnant much faster than the Milky Way is moving relative to the CMB!

But how fast is it moving relative to the Library of Congress?
