Astronomy
Stellar Distance Calculator
Convert a star's measured parallax angle into its distance in parsecs, light-years, or astronomical units. Essential for students and astronomers interpreting Hipparcos or Gaia catalog data.

Astronomy
Stellar Lifetime Calculator
Estimate how long a star spends on the main sequence based on its mass relative to the Sun. More massive stars burn through fuel faster, living far shorter lives than smaller stars.
