Calculate astronomical distances using redshift values
Redshift is a measure of how much light is shifted towards the red end of the spectrum as it travels through space. It's a key indicator of the universe's expansion and can be used to estimate the distance of celestial objects.
The redshift distance estimator calculator uses the Hubble constant (H0) to calculate the distance of galaxies and other objects based on their redshift values. The Hubble constant is a measure of the rate at which the universe is expanding [1].
Enter the redshift value (z) of the celestial object you're interested in, and the calculator will provide an estimate of its distance in megaparsecs (Mpc). The calculation is based on the formula: d = z*c/H0, where d is the distance, z is the redshift, c is the speed of light, and H0 is the Hubble constant.
| Redshift (z) | Distance (Mpc) |
|---|---|
| 0.1 | ≈ 430 |
| 0.5 | ≈ 2,300 |
