Muon Mass
The muon is an elementary particle similar to the electron but heavier. Its rest mass is approximately 1.884 × 10⁻²⁸ kilograms (or about 105.7 MeV/c² in energy units).
Muons are unstable and decay into electrons and neutrinos but play a key role in particle physics and cosmic ray interactions.
Summary:
Rest mass ≈ 1.884 × 10⁻²⁸ kg
Equivalent to about 105.7 MeV/c²
Heavier cousin of the electron in particle physics
