interesting phenomenon

What is it made up of?

• Star

• Planets

• Comets

• ??????????????

Stars

• What is a Star?– A star is a massive, luminous ball of reacting

gas– All stars have a life cycle which takes billions

of years– Our Sun is a star, but just one of many

millions in our galaxy

• Scientist know they are different by using a special diagram which relates temperature to the type of star

Red Supergiant

White

Dwarf

Giant Star

Galaxies

• Each galaxy is made up of several star systems

• The universe itself is made up of many billions of galaxies

• Scientists are able to photograph them from Earth and in space using the Hubble Space Telescope

Planets

• Our solar system contains eight planets, with each one orbiting the Sun

• Many of the planets have moons which orbit around them

• Planets were named after Romans and Greek gods

• Other galaxies have planets, but they are very hard to find

• The planets have an order worked out from the closeness of their orbit to the Sun

• Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.

• BUT WHAT ABOUT PLUTO?

• Eris was a planet discovered in 2003 in the solar system that is larger than Pluto

Moons

• Moons are satellites that orbit planets

• The Earths Moon is simply known as the moon – but other planets have moons with proper names

• Jupiter has lots of Moons – we know lots of details about the inner four – Callisto, Io, Ganymede and Europa at this stage.
