Pluto The Pup

In the end stages of planet formation, a planet will have “cleared the neighbourhood” of its own orbital zone, meaning it has become gravitationally dominant, and there are no other bodies of comparable size other than its own satellites or those otherwise under its gravitational influence. A large body which meets the other criteria for a planet but has not cleared its neighbourhood is classified as a dwarf planet. This includes Pluto, which shares its orbital neighbourhood with Kuiper belt objects such as the plutinos. The IAU’s definition does not attach specific numbers or equations to this term, but the extent to which all the planets have cleared their neighbourhoods is much greater, by any measure, than that of any dwarf planet or any candidate for dwarf planet known so far.

Frontiers/Controversies in Astrophysics (ASTR 160) Class begins with a review of the first problem set. Newton’s Third Law is applied in explaining how exoplanets are found. An overview of the Solar System is given; each planet is presented individually and its special features are highlighted. Astronomy is discussed as an observational science, and the subject of how to categorize objects in the Solar System is addressed. The Pluto controversy is given special attention and both sides of the argument regarding its status are considered. 00:00 – Chapter 1. Review of the Problem Set 06:22 – Chapter 2.

What is a Trans-Neptunian Object (TNO) Plutoid?… Any object orbiting the sun beyond Neptune are called ‘Trans-Neptunian Objects’. When it’s a Dwarf Planet orbiting beyond Neptune, it’s then called a ‘Plutoid’. I will be making a video about this in the future. I didn’t find alot of interesting facts about Dysnomia, however here is a few links to websites with facts about Eris’s moon, Dysnomia: www.absoluteastronomy.com en.wikipedia.org If you know anything interesting about these dwarf planets, feel free to share them in the comments! 🙂 Please rate, comment and subby!! xx

Science & Reason on Facebook: tinyurl.com Hubble’s Universe Unfiltered 15: Changing Views of Pluto While it may seem that the astronomy community’s views on Pluto changed radically with its reclassification in 2006, the truth is that our understanding of Pluto has always been shifting. This small, icy world in the distant reaches of the solar system is so difficult to observe that, even with Hubble’s keen resolution, it only shows up as a few pixels in an image. Only with patience, lots of observations, and huge amounts of computing power have we been able to create approximate surface maps of Pluto and discover some surprising alterations to its surface. Improved imagery yields improved insight. We now comprehend Pluto’s place within the solar system, and the exploration of that region has really just begun. Hubble’s Universe Unfiltered is a collection of video podcasts. Each episode offers an in-depth explanation of the latest news story or image from the Hubble Space Telescope, presented by astronomer Frank Summers. — Please subscribe to Science & Reason: • www.youtube.com • www.youtube.com • www.youtube.com • www.youtube.com — NOTES * In the video podcast, I jokingly refer to “Percival Lowell’s Greatest Mistakes” being 1.) the claim that Mars had a civilization using canals, and 2.) the prediction of a large planet beyond Neptune. Some may recognize this phrasing as an oblique reference to similar wording used in Douglas Adams’ Hitchhiker series. (If you’re going …
