'''புரோக்சிமா செண்ட்டாரி''' (Proxima Centauri, அருகாமையில் இருப்பது) என்பது சூரிய மண்டலத்தின் சூரியனுக்கு மிக அருகில் இருக்கும் [[விண்மீன்]]. இது ஒரு சிறு நட்சத்திரம் ஆகும். இது பூமியிலிருந்து 4.2 [[வெளிச்ச ஆண்டு]]கள் தூரத்தில் உள்ளது. புரோக்சிமா செண்ட்டாரி செங்குறளி (red dwarf) விண்மீன் வகையைச் சேர்ந்தது

புரோக்சிமா செண்ட்டாரி (Proxima Centauri, அருகாமையில் இருப்பது) என்பது சூரிய மண்டலத்தின் சூரியனுக்கு மிக அருகில் இருக்கும் விண்மீன். இது ஒரு சிறு நட்சத்திரம் ஆகும். இது பூமியிலிருந்து 4.2 வெளிச்ச ஆண்டுகள் தூரத்தில் உள்ளது. புரோக்சிமா செண்ட்டாரி செங்குறளி (red dwarf) விண்மீன் வகையைச் சேர்ந்தது

Explanatory notes

  1. From knowing the absolute visual magnitude of Proxima Centauri, , and the absolute visual magnitude of the Sun, , the visual luminosity of Proxima Centauri can therefore be calculated:
