back to article Don't stare: SHRUNKEN Mercury lost 7km, but only 'cos it's COOLING

The planet Mercury has shrunk by up to 7km in radius over the past four billion years – much more than boffins had previously thought. A long collection of ridges and scarps on the planet Mercury, stretching over 540km. The colours correspond to elevation - yellow-green is high and blue is low. Ridges and scarps on Mercury, …

You should ask your mum. She knows this sort of thing.
