1. Look up the parallax of star HIP 70890 on the SIMBAD astronomical database at http://simbad.u-strasbg.fr/simbad/sim-fid. A. What is its parallax specified on this website in mas? B. What is the star's distance from the Earth in parsecs? C. If this star vanished right now, when will we find out? D. The New Horizons Spacecraft journeyed to Pluto at a speed of about 15 km/s. At this speed, how long would it take to go from Earth to this star (which, by the way, is Proxima Centauri, the closest known star to the Sun)?
