Hence define the parsec, and calculate its value in astronomical units and metres. The star Betelgeuse is observed to have a parallax angle p = 4.5 x 10-³ arcseconds. State the distance of Betelgeuse in units of parsecs and light years.arrow_forwardHelp me please.

Why is that the case? What is the altitude of the celestial equator at its highest point as viewed from this location and how do we calculate that? Explain the myth behind one of the constellations located near North Celestial Pole and then explain the myth behind another constellation along the ecliptic plane.arrow_forward
