Inert inactive asteroids orbit the Sun following the law of gravity whereas active asteroids can emit little rocket like bursts of gas which can change their path about the Sun in interesting ways. It is important to study objects like 467P (LINEAR-Grauer) to make sure their path about the Sun doesn’t change to make them a threat to our home planet.","meta_description":"Astronomers using the 8.1 m Gemini South Telescope in Chile were excited by the fact that 467P (LINEAR-Grauer)’s Centaur like orbit had been changed as th…","key_points":[],"chapters":[],"topics":[],"duration_seconds":121,"processing_state":"not_requested","actions":[{"name":"request_transcript","method":"POST","url":"https://stenobird.com/v1/public/podcasts/travelers-in-the-night-1048610/episodes/890-comet-467p-linear-grauer/transcription-requests","description":"Idempotently request low-priority transcript generation for this episode."},{"name":"read_markdown","method":"GET","url":"https://stenobird.com/podcast/travelers-in-the-night-1048610/890-comet-467p-linear-grauer.md","description":"Read the agent-friendly Markdown representation of this episode resource."}]}}
