Sirius is approximately 2.6 parsecs or 8.6 light years away from Earth.
A distance of one million parsecs (approximately 3,262,000 light-years) is commonly denoted by the megaparsec(Mpc).
The parallax angle of Sirius is approximately 0.38 arcseconds. This value indicates the shift in position of the star as seen from Earth due to its motion around the Sun. The parallax angle is used to calculate the distance to nearby stars.
Absolute magnitude is based on the distance at which a star would appear if it were located at a standard distance of 10 parsecs (32.6 light-years) from Earth. This standardized distance allows astronomers to compare the true brightness of stars regardless of their actual distance from Earth.
Sirius is approximately 8.6 light-years away from Earth, which is equivalent to about 8.2 parsecs or 25.4 trillion miles. This translates to roughly 8.6 x 10^4 astronomical units (AU).
The distance to the star can be calculated using the parallax angle (in arcseconds) and the formula: distance (in parsecs) = 1 / parallax angle (in arcseconds). Given a parallax of 0.75 arcseconds, the star is approximately 1.33 parsecs away. Converting parsecs to light years (1 parsec ≈ 3.26 light years), the star is about 4.34 light years away.
The distance from Earth to Sirius is the reciprocal of its parallax angle, so it would be 1 / 0.377 = 2.654 parsecs away.

Sirius is actually a binary system.At a distance of 2.6 parsecs (8.6 light years), the Sirius system is one of our near neighbours.This equates to approximately:5 x 1013 miles8.1 × 1013 kilometres543,861 AU.
Light years or Parsecs
A distance of one million parsecs (approximately 3,262,000 light-years) is commonly denoted by the megaparsec(Mpc).
The distance from Earth is about 6,500 light years (2000 parsecs).
Light years (the distance that light travels in one year) and parsecs, which is approximately equal to 3.26 light years. For very distant objects, the units of "mega-parsecs" (millions of parsecs) are sometimes used, sometimes abbreviated as "Mpc".
