Quand la comète de Halley reviendra-t-elle ?<end_of_turn>
<start_of_turn>model
It passes close to the sun approximately every 76 years and should reappear in our sky in 2062 - its last passage dates from 1986. Astronomers know its route well: Halley orbits the Sun following a very elongated trajectory which takes it up to to the confines of the Solar System and then tirelessly returns it to the vicinity of the Earth and the Sun, for at least millennia.<end_of_turn><eos>
