Question

the cosmic distance ladder is an overlapping chain of techniques used for measuring astronomical distances. the accuracy of each step in the ladder depends on the accuracy of all the steps below it. re - create the ladder by placing the items or methods involved in measuring the distances from farthest to closest. farthest rr - lyrae stars type ia supernovae hubble constant parallax radar measurements of planets closest

Explanation:

The Hubble constant is used for the most distant objects in the universe, followed by type Ia supernovae which are standard - candles for measuring large extragalactic distances. RR - Lyrae stars are also standard candles but for closer distances compared to the previous two. Parallax is used for nearby stars, and radar measurements of planets are for the closest objects in the solar system.

Answer:

Hubble constant, type Ia supernovae, RR - Lyrae stars, parallax, radar measurements of planets
