It's Called an Asterism, Ron

Weasley pointed west. ‘What star's that?’

Miss Granger sighed. ‘That’s the planet Venus.’

‘Oh,’ Weasley muttered. He pointed again. ‘What about that one?’

‘The … moving one?’

‘Yeah.’

‘There’s a reason we call the stars “fixed,” Ron. That’s a satellite.’ Granger stomped towards the stairs. ‘Why don’t I get the star book by the bloke who wrote Curious George for you so I don’t have to spend all night up here? Next you’ll be calling Orion's Belt a constellation!’

The ginger gonk scarpered after her.

Severus smirked. He’d stop by Aurora’s office and suggest an impromptu quiz for the fifth-years tomorrow.
