I have been searching the Internet about the two newest planets
discovered, Sedna and Eris. But the people writing about them seem too arrogant about them being too small to be planets to admit they are planets. I can't even find a model or map of the Solar System with the orbits of these two new planets on them. Since scientists started trying to re-classify certain planets into being dwarf planets, seems we just can't get anything straight about the Solar System anymore. Thank goodness a few of the web sites still talk about the Nine Planets, including Pluto! So how many planets do we now have? 9? !0? 11? Maybe no one knows. |

I googled: map of solar system showing dwarf planets First hit was http://www.vtaide.com/png/solar-system.htm To be fair, although it does show Eris and Ceres, it doesn't show Sedna, Haumea or Makemake, and it's surely not to scale. But it at least gives a feel for the order of things, heading out from the sun. So how many planets do we now have? 9? 10? 11? Maybe no one knows. 8 planets, 5 dwarf planets[1], and dozens, maybe even hundreds of objects - including Sedna - that we haven't yet been able to observe well enough to determine whether they have a near-spherical shape[2]. The number of non-dwarf planets in our solar system seems likely to remain at 8. The number of dwarf planets, though, seems certain to increase, and likely to reach the point where no one can remember them all, any more than anyone can remember the names of all the comets, or all the asteroids.

Thanks for the information about the current consensus. But I grew up with big beautiful maps of the nine planets, including Pluto. It was so neat to think of Pluto as a rogue planet, possibly escaping from Neptune and going within Neptune's orbit. Now we discover two more rogue planets, Sedna and Eris. They ought to have the same status as Pluto once had. They orbit the Sun on their own, just like planets do. Leave the asteroids to the asteroid belt, they don't need to be promoted to the status of planets of any type. They are just rubble, and probably run into one another every once in awhile, making even more rubble. As soon as I get an orderly map of the Solar System, then I will feel more certain that knowledge of the Solar System is in order, where even first graders can learn about all the planets, like I did. Everyone wants to rule reality, and astronomers want to rule the reality of the planets. They're not ruling my reality. |

My dearest Mark,

I can't even find a model or map of the Solar System with the orbits of these two new planets on them.

Thank goodness a few of the web sites still talk about the Nine Planets, including Pluto! So how many planets do we now have? 9? !0? 11? Maybe no one knows. There are still many things we don't know about those faraway objects to be able to clarify how to classify them. Pluto was considered a planet when we were kids mainly because 1) it was thought to be all alone out there, 2) it had originally been thought to be a gas giant, and 3) it was the only planet that had been discovered by an American. The movement to get Pluto reclassified away from being a planet actually began shortly after it was discovered by Clyde Tombaugh. It didn't take long for astronomers to realize that Pluto was a whole lot smaller than originally thought. Getting Pluto reclassified was tougher than they thought it would be, though, and it wasn't really until other TNOs were discovered beginning in 1992 that the movement to reclassify Pluto took on some momentum. Mark, it's just a matter of wanting to be as precise as possible when it comes to definitions, that's all. It's not easy to accept change when it's needed. Man up ! Officially, there are eight planets in the Solar system. As you might remember, i still consider there to be nine... Mercury Venus Earth Selene Mars Jupiter Saturn Uranus Neptune Selene (the Moon) is a full-fledged planet in its own right... http://selene.painellsworth.net Happy days *and*...
