Wolf 359 -- Nearby Star
From the author of
Sizing Up
The Universe
Animated gif showing comparison of my picture taken here on Earth and the New Horizons picture taken from 50 AU away.
I rescaled and aligned the New Horizons image of Wolf 359 with my image of the same. I used the known pixel size of my image to compute the parallax
angular shift in these two images to be 16.7 arcseconds.
The distance to Wolf 359 is known to be 2.409 parsecs. And, the angular separation in the sky between Wolf 359 and New Horizons is 125 degrees.
Using the above information, we can compute the distance to the New Horizons...
