Is there really an up/down, left/right, north/south in space?

directions are three dimensional in space, (perhaps more) and the up/down, left/right, north/south directions refer more to two dimensional maps.

Pluto misses you as well, and sends its’ love.

I guess we just go by Earth’s north/south… etc…

Did they actaully decide to get rid of Pluto? I thought they decided to keep it as a planet even though it does not really meet the standards of a Planet? How is it classified now?

Pluto is a dwarf planet. In space there really are 4 dimensions, the fourth one being time. For example the sun that we see can be located by some 3 dimensional coordinate but what we see was the sun 8 minutes ago.

Up, down, left, and right generally refers to 2 dimensions and can be utilized but only relatively speaking.

@critter1982 Are there many dwarf planets?

No there’s not many. I think 5.

“Is there really an up/down, left/right, north/south in space?”

Only relatively speaking. Generally it would be based on the orientation of the Earth for us at any rate, or for one’s home planet if you aren’t from here. Most science fiction stories seem to have also carried on the 24-hour day and the 365-day year, even though that only obtains on planets with the same orbit and orbital speed as Earth.

No.
I miss Pluto too.

So….I can hang this sexy Jupiter poster upside down if I please?

@kikibirdjones – Absolutely. How do you think the folks in the Southern Hemisphere (replace with Northern Hemisphere if you are from south of the equator) see it?

I also miss Pluto. And Goofy.

Austrailian maps are upside down (to us).
There are many dwarf planets in our solar system. Possibly 200.

Hey guys, Pluto may not be a planet like Earth anymore, but it’s still there for you. This doesn’t mean Pluto doesn’t love you anymore. It’s just that Earth and Pluto couldn’t make it work out together.

@filmfann: According to the not so scientific Wikipedia and a few other websites the IAU has classified only 5 planets as dwarf planets. Ceres, Pluto, Haumea, Makemake, & Eris. Apparently, there is about 200 still being analyzed in the Kuiper Belt, but have not yet been confirmed.

@filmfan Are they really???

@critter1982- Charon isn’t on that list?

@AstroChuck: When did you get color?

Also from the not so scientific Wikipedia “In a draft proposal for the 2006 redefinition of the term, the International Astronomical Union proposed that a planet be defined as a body that orbits the sun that is large enough for gravitational forces to render the object (nearly) spherical. Under this proposal, Charon would have been classified as a planet, since the draft explicitly defined a planetary satellite as one in which the barycenter lies within the major body. In the final definition, Pluto was reclassified as a dwarf planet, but the formal definition of a planetary satellite was not decided upon, leaving Charon’s status unclear. (Charon is not in the list of dwarf planets currently recognized by the IAU.)”

@critter1982- I’ve gone orange for cak.

I’m still not satisfied!
