B What is the Unit for Gas Giant Planets in Astrophysics?

AI Thread Summary
The unit ⊕ represents Earth masses in astrophysics, indicating that >10 M⊕ refers to more than ten times the mass of Earth. This notation is commonly used to classify gas giant planets. Additionally, a circle with a dot instead of a plus sign denotes solar masses, which is a different measurement. Understanding these units is crucial for interpreting the mass and classification of celestial bodies. The discussion clarifies the significance of these symbols in astrophysical contexts.

Earth masses. So >10 M⊕ is more than 10 Earth masses.

If you see one that is a circle with a dot instead of a plus, that means Sun.

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...
