Meteorites, asteroids & comets
There are important differences between meteors, meteorites, asteroids and comets. Get to know them all with our expert views.
Is that space rock?
From pebbles on Brighton Beach to the granite of the Highlands - the UK is covered with rocks. How do you know if the stone in your hand has come from space? Check Rob's tips for recognising a meteorite.
Just another rock?
So, you think you've found a meteorite? Congratulations! But are you sure that's what it is? Some everyday rocks can look quite similar. Our guide can help you decide: Is it a meteorite?
Rites and wrongs
So, you've found a promising looking example - but is it really a rock from beyond this planet? A simple test can tell if what you've found is a meteorite - or a meteor-wrong.
Was it a meteorite?
The Great Biritsh Meteorite Hunt saw thousands of you out seeking for space rocks. Dr Matt Genge reports on how you got on in was it a meteorite?
What are they called?
In one sense, the Beatles are out of this world. With so many chunks of rock orbiting in the solar system, agreement had to be reached on how to keep track of them. Discover how they set about naming asteroids.
Threat or blessing?
If an asteroid heads our way, should we take evasive action - or grab our mining equipment? While some make plans to save the planet, others are plotting to make a killing. Should we be planning to avoid or exploit?
Closer to comets
They're very distinct from asteroids and meteorites. Discover more about comets - the what, where and why.
What's the impact on you?
Will the scientific insights given by smashing a spaceship into a comet be worth the costs? Is the chosen day a little too symbolic? We want to hear your views - science or stunt?
