Study Notes
Celestial Bodies and Phenomena
- Light travels at a speed of approximately 299,792,458 meters per second.
- A constellation is a group of stars that, when connected, form a pattern or shape on the celestial sphere.
Stars and Planets
- A fixed star is a celestial body that is stationary relative to the Earth, while a planet is a celestial body that orbits the Sun.
Atmospheric Phenomena
- Aurora borealis, also known as the northern lights, is a natural light display in the Earth's polar regions, caused by charged particles from the Sun interacting with the Earth's magnetic field and atmosphere.
The Earth and its Neighbour
- The Earth's nearest celestial neighbour is the Moon.
- The average distance from the Earth to the Sun is approximately 149.6 million kilometers.
Tides and Eclipses
- Tides are governed by the gravitational pull of the Moon and the Sun on the Earth's oceans.
- An eclipse occurs when one celestial body passes through the shadow of another, such as the Moon passing through the Earth's shadow during a lunar eclipse, or the Earth passing through the Moon's shadow during a solar eclipse.
