Renu Malhotra (born 1961) is an American planetary scientist from India, known for using the orbital resonance between Pluto and Neptune to infer large-scale orbital migration of the giant planets and to predict the existence of Plutinos in resonance with Neptune. The asteroid 6698 Malhotra was named for her on 14 December 1997 (M.P.C. 31025). Francis and Dr. Malhotra discuss the latest information coming from the scientific community regarding the discovery of yet to be discovered planetesimals Planet 9 and Planet 10 (X). Hear how the work she and other scientists are performing are giving us a better understanding of far-flung objects residing out near Neptune. These objects are so far away and so dispersed that even with years of observing the motion of known planets and transient objects, the information still doesn't point a finger at any particular object or place in the solar system. Learn how the presession of the planets effects orbits of small rocky bodies orbiting inside the solar system. We touch on the gas giants' migration during the early times of the solar system, and we discuss the "Great Bombardment" as well. This was an enlightening discussion, and we hope to hear more from Dr. Malhotra again soon! So, STAY TUNED! As always, please like, follow, comment, and review the Collision Course podcast whenever asked as it helps us reach more listeners! Thanks for all your help and for your friendship! We have many more episodes coming as we get ready for the total solar eclipse of April 8th, 2024! #planetnine #planetten #planetX #planetary #astronomy   For direct donations go to: $FrancisWalsh @FrantheMan77429   ---   Send in a voice message: https://anchor.fm/collision-course/message

Planet 9 and 10 (X) with Dr. Renu Malhotra - Are There Two, Unidentified Planetesimals Hiding Out in Our Solar System?

My guest today is Dr. Renu Malhotra, a planetary scientist who specializes in planetary migration and orbital mechanics. Dr. Malhotra and her team have discovered that Pluto's orbit is surprisingly chaotic at small timescales and yet surprisingly stable at larger timescale. We'll talk about her research and the science of orbital mechanics that led to the current orbits of the planets in the Solar System. https://www.lpl.arizona.edu/~renu/ 🚀 OUR WEBSITE: ════════════════════════════════════ https://www.universetoday.com/ 🚀 PODCAST LINKS: ════════════════════════════════════ RSS:                https://universetoday.com/audio iTunes:           https://universetoday.com/itunes Spotify:          https://universetoday.com/spotify 🚀 EMAIL NEWSLETTER: ════════════════════════════════════ Read by 50,000 people every Friday.

813: Weird Orbits and How They Work with Dr. Renu Malhotra

Our understanding of the history of the solar system has undergone a revolution in recent years, owing to new theoretical insights into the origin of Pluto and the discovery of the Kuiper Belt and its rich dynamical structure. The emerging picture is one of dramatic orbital migration of the planets in the early history of the solar system, driven by interaction with the primordial Kuiper Belt, which produced the final solar system architecture that we live in today. The evidence is all over the solar system, as close as the Moon and as far away as Pluto and the remnant Kuiper Belt. Dr. Malhotra will review this new view of our solar system's history, describe the astronomical evidence, and critically assess current theoretical models.
