Formulas
$$T_{synodic} \approx 29.5 \; \text{days}$$
Synodic month: period from new moon to new moon
$$g_{moon} \approx 1.6 \; \text{m/s}^2$$
Gravitational acceleration on the moon's surface
Units
| Day | d |
Interesting Fact
A lunar month (29.5 days) is the time for the moon to go through all phases
Key Scientist
Isaac Newton
Explained tides through universal gravitation
Modern Research
Lunar geology from Apollo samples and current orbital missions reveal the moon's ancient history and its role in Earth's climate regulation.
