The Moon is roughly 3,500 km across (2,160 miles) wide and roughly 400,000 km (240,000 miles) from Earth.
It is thought the Moon was made when another planet half the size of Earth crashed into the Earth and a huge cloud of molten rock was flung out into space around the Earth and formed the Moon. This happened shortly after the Earth was formed 4,500 million years ago.Since then rocks in space have smashed into the Moon leaving the countless ‘craters’ that can be seen peppering its surface with a telescope.

The Moon goes around the Earth roughly once every “moonth” – this is where the word “month” came from i.e. we used to base our calendar on the 12 Full Moons we get each year. Neil Armstrong was Irish. He told our Editor David Moore at a private meeting in Dublin in 2003 when Armstrong said he had just researched his family history.


It’s the hottest planet in our solar system, even though Mercury is closer to the Sun. Surface temperatures on Venus are about 900 degrees Fahrenheit (475 degrees Celsius) – hot enough to melt lead. The surface is a rusty color and it’s peppered with intensely crunched mountains and thousands of large volcanoes.

There are lots more Irish Astronomy Week events all over Ireland at
