It would take almost 2 years for the fastest human-made spacecraft to The Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, designed, built and operates the New Horizons spacecraft, and manages the mission for NASA's Science Mission Directorate. },false) Its orbit through our galaxy will take it within 20,500 light years of the Galactic Centre and as far away as 28,000 light years. }); [45][46], The rotation of a star causes a Doppler shift to the spectrum. (B) another telescope is used to observe the same star in the visible part of the spectrum. The American astronomer Frank Elmore Ross first cataloged it in 1925 as part of his search for variable stars. A study published in 2005 derived an age between 200 and 350 million years for the star based on modelling its spectral energy distribution and on the results of a 1993 study that had not detected any lines of lithium in the spectrum of Wolf 359.
