Distance

Hunting For Asteroids

Aimed at pupils aged 11-14 this workshop encourages pupils to ‘blink’ between several images, taken by the Liverpool Telescope, in a bid to find asteroids. The activity can then be extended to them using the LT Image software functionality to calculate the speed of the asteroids, or simply a discussion on what asteroids are and how we track them.

You can download the individual files needed for this activity below, or this zip file (53mb) contains them all.

The light-year is a way of measuring distance - and not time as you might think from the name.

It is the distance that light travels in one year.
