A star that has a parallax of 0.047 arcseconds is 69.38 light years away from the Earth.

What is the distance of a star with parallax 0.047 seconds?

The distance of a star with parallax 0.047 seconds is determined by finding the distance of 1 parsec.

For a star that has a parallax of 0.047 arcseconds, the light-years away from the earth can be computed by using the formula:

[tex]\mathbf{Parsec = \dfrac{1}{arcsecond}}[/tex]

[tex]\mathbf{Parsec = \dfrac{1}{0.047}}[/tex]

[tex]\mathbf{Parsec =21.28 }[/tex]

Recall that:

  • 1 Parsec = 3.26 light years

Thus;

21.28 Parsec = (21.28 × 3.26) Light years

= 69.38 light years
