According to ground-based observatories on Earth, the parallax of the star Proxima Centauri is p = 0.77 arcsec. There's a planet orbiting this star at distance r = 0.05 au (assume its orbit is approximately circular). Let's imagine there are intelligent beings living on this planet (let's call them Centaurs) and they measured the parallax of our Sun. The Centaurian definition of the parallax is, of course, based on their home planet's orbit. How large is the parallax they measured? Enter the result in arcseconds.
