Study Notes
Earth, Sun and Moon
- The solar system consists of planets, moons, asteroids, meteors and comets, orbiting the Sun.
- The Moon orbits the Earth in 27.3 days.
- The Earth orbits the Sun in 365.25 days.
Our Solar System
- The Sun is the closest star to Earth and provides energy for all life.
- Energy is created in the Sun through atom collisions.
- This energy is called Solar Energy.
Day and Night
- The Earth spins on its axis, an imaginary line through the North and South Pole.
- One rotation takes 24 hours, resulting in day and night.
- The Earth's shape exposes only half of the planet to sunlight at a time.
- The half facing the Sun experiences day and the opposite half experiences night.
A Year
- A year is the time it takes for a planet to orbit the Sun.
- The Earth takes 365.25 days to orbit the Sun.
- To account for the extra 0.25 days, a leap year with 366 days occurs every four years.
Solar Eclipse
- A solar eclipse occurs when the moon passes between the Sun and Earth.
- This happens every 27.3 days.
- During a total solar eclipse, the Moon blocks the Sun completely.
- During a partial solar eclipse, the Moon blocks only part of the Sun.
- The last total solar eclipse visible in Northern Australia was on 13 November 2012, the next will be on 20 April 2023, visible in Western Australia.
