The planets spin as they orbit the sun. It takes the earth 24 hours to make a complete turn on its axis, this is why a day in the UK is 24 hours long. In the day time we are facing the sun and at night we are facing the sun.
Uk in the summer the sun is tilted on the axis facing the sun therefor we gain more heat.
In uk in winter the earth is tilted away from the sun giving us less heat and light energy.
comets are made in a huge cloud called a oort cloud.
they are made from frozen gases and dust.
sometimes a comit is spat out from the oort cloud so it can orbit the sun.
as the comet gets nearer to the sun it breaks apart.
cmets have tails.
