What unit is used to measure volume in space?

AI Thread Summary
The unit commonly used to measure volume in space is the cubic light-year, analogous to the cubic meter used on Earth. For extremely large volumes, cubic parsecs are often utilized. Light-years measure distance, while cubic light-years and cubic parsecs quantify three-dimensional space. These units help astronomers and scientists communicate vast spatial dimensions effectively. Understanding these measurements is crucial for studying the universe's structure and scale.

While reading another thread it occurred to me - what unit is used to measure volumn in space? I know light-years are used to measure distance, so is it 'cubic light-year', ala 'cubic meter'?

Cubic light years is the most common measure. For REALLY large volumes cubic parsecs is often used.

Thread 'Asteroid 2024 YR4 has a 1% risk of a multi-megaton impact in 2032 (now ruled out)'

Asteroid, Data - 1.2% risk of an impact on December 22, 2032. The estimated diameter is 55 m and an impact would likely release an energy of 8 megatons of TNT equivalent, although these numbers have a large uncertainty - it could also be 1 or 100 megatons. Currently the object has level 3 on the Torino scale, the second-highest ever (after Apophis) and only the third object to exceed level 1. Most likely it will miss, and if it hits then most likely it'll hit an ocean and be harmless, but...
