Supernova light model vs Moon orbital kinetic energy: energy comparison
The energy of a supernova light model is about 2.61 × 10¹³ times the Moon’s orbital kinetic energy.
ENERGY STORED OR TRANSFERRED
The electromagnetic energy released by a typical supernova explosion, excluding kinetic and neutrino energy.
Moon orbital kinetic energy is the energy the Moon possesses due to its motion as it orbits Earth.
Too small to see at this scale; the bar has not been widened.
Measurements, assumptions & sources +
Supernova light model
Energy: 1 × 10²⁷ PJ; defined energy model.
An illustrative 10⁴² J electromagnetic-energy budget. Explosion kinetic energy and neutrino energy are separate.
Defined examples — our methodology
The marked energy is calibrated. Unmeasured illustration details are representative.
Moon orbital kinetic energy
Mean-orbit kinetic energy: 3.83 × 10¹³ PJ; derived; range 3.7 × 10¹³ PJ–4 × 10¹³ PJ.
Approximately 3.83 × 10²⁸ J, calculated as ½mv² from the JPL-derived lunar mass and a mean orbital speed of 1.022 km/s. The Moon’s elliptical orbit changes its instantaneous speed and kinetic energy.
The marked mean-orbit kinetic energy is calibrated. Unmeasured illustration details are representative.

Why we use 1 × 10²⁷ PJ
We compare the energy of a supernova light model. This is an illustrative comparison value, not a claim that every example is the same.
