Speaker Meeting

Comets Asteroids and impacts. Should we worry?
Friday 16th December 2022
Start time : 20:00

Speaker : Dr Robin Catchpole

Look up at the night sky for a while and you will see a streak of light, as a meteor, the size of a grain of sand, burns up in our atmosphere. On average, every 5000 years an object, large enough to make a crater 1 km in diameter, strikes the Earth. We will look at past impacts, including that of 1906, that demolished 40 million trees, which may be related to even larger events in the last 10 000 years. We will examine the origin of these impacts and see what we are doing to predict and prevent them.

This will be held in person at the Institute of Astronomy - doors open 7:30pm
