The Sun orbits around the Galaxy at a radius of about 8.5 kpc. In a mere 110 million years from now, the Sun will be on the other side of the Galaxy. The nearby galaxies will appear to shift in the sky relative to more distant background galaxies - a galactic parallax. What would be the number of parsecs in a 'galsec,' the distance of a galaxy whose galatic parallax equal 1.0"?
Astronomy question - help!!?
