The planets in order based on their distance to the sun (near to far)

Inner Planets

Outer Planets

Difference between rotation and revolution

What makes a planet a planet

Characteristics of Inner and Outer Planets

mercury

venus

earth

mars

jupiter

saturn

uranus

neptune

planets and asteroids take different amounts of time to revolve around the sun

our solar system

moons

moons surface

moons

give three ways in which gas giants differ from other planets

rotation

earth spins on its own axis

rotation of the earth causes night and day

plsnets revolve around the sun in their own orbits

the earth revolves around the sun in its own orbit in 365 and a quarter days = a year

rotation of the moon

revolution of the moon

the movement of a body in space around another body is called

the movement of an object in space around its own axis is called

the path in which an object moves round another is called its

the time for the earth to revolve around the sun is called a

the time taken for the moon to revolve around the earth is called a

the imaginary line through the centre of the earth is called its

telescope

lens

telescope invented by

optical telescopes=
radio telescopes =

radio telescopes can only collect a small amount of information so we need a group of telescopes called

array

earth's atmos[here stops us getting perfect images from space so send telescopes to space that work as satelites
most famous space satellite is

telescopes in South Africa
have best conditions for observing space = plenty of good weather, clear skies, places away from lights if buildings and pollution

Rovers on the moon and Mars

how a telescope works

exploring the moon
