What is HIP 91461
Telescopium —the constellation Lacaille named in honour of the instrument that revealed it— holds this A-type white at 357 light-years. Its light crossed the vacuum while Newton was grinding his first reflecting telescopes in Cambridge and opening a new way to observe the sky. It took three and a half centuries to reach the eye waiting for it.
