Nine Reasons Why Pluto Is a Planet - Philip Metzger

Planetary scientist Phil Metzger has written a very comprehensive, logical article titled"Nine Reasons Why Pluto Is A Planet," and his is one of the best-written articles I have read on this subject in nearly a decade. It successfully rebuts many arguments used by supporters of the IAU definition. I highly recommend all Pluto supporters take the time to read this and learn about why Pluto is not a comet, is not too small to be a planet, and much more.

New Horizons briefings tomorrow will be broadcast live on NASA TV

In his latest PI Perspective at http://pluto.jhuapl.edu/News-Center/PI-Perspectives.php?page=piPerspective_04_13_2015 , New Horizons Principal Investigator Alan Stern discusses the beginning of the mission's Approach Phase 2, which started on April 5.

Tomorrow, Tuesday, April 14, NASA will conduct two briefings on the New Horizons mission, both of which can be viewed live on NASA TV at http://www.nasa.gov/multimedia/nasatv/index.html . The first will be at 1 PM Eastern Daylight Time (adjust for other time zones) and is titled, "New Horizons Media Briefing: Seeing Pluto as Never Before (all channels)." The second will be at 2:30 Eastern Daylight Time (adjust for other time zones) and is titled, "New Horizons Media Briefing: Getting to Pluto (NTV-3 (Media))."

The briefings will also be broadcast on this site: http://www.parabolicarc.com/2015/04/13/nasa-tv-air-horizons-briefings-tuesday/

Recordings of the both briefings will be available on NASA TV for those whose schedules do not permit them to watch the briefings live.

I also discuss Approach Phase 2 in my latest article for "Spaceflight Insider" at http://www.spaceflightinsider.com/missions/solar-system/new-horizons-begins-approach-phase-2/

Another Poll! Vote Yes, Pluto is a Planet!


Results of this poll will be sent to the IAU. Currently, the results are 54 percent for Pluto and 46 percent against.

The site presents arguments for both sides of this debate. Interestingly, it erroneously attributes the discovery of Eris solely to Mike Brown, when the reality is that Eris was discovered by a team of three astronomers, the other two being Chad Trujillo and David Rabinowitz. Significantly, Rabinowitz signed Alan Stern's petition rejecting the IAU planet definition and demotion of Pluto.
