Suppose there was a star with a parallax angle of 1 arcsecond. How far away would it be? Select all that apply.
A) 1/3.26 light-years
B) 1 light-year
C) 3.26 parsecs
D) 32.6 light-years
E) 3.26 light-years

Respuesta :

Answer:

option E

Explanation:

given,                          

Parallax angle(d) = 1 arcsecond

using Parallax formula                  

      [tex]d = \dfrac{1}{p}[/tex]

 p is the parsecs angle which is measured in 1 arcsecond

 d is the distance in parsec

now,                                            

      [tex]P = \dfrac{1}{d}[/tex]

      [tex]P = \dfrac{1}{1}[/tex]

      [tex]P = 1 \ parsec[/tex]

we know,                                  

    1 parsec = 3.26 light year

hence, the answer will be option E
