Does Planet 2003UB313 (the new planet slightly larger from Pluto) can be seen with a naked eye?

Question

I really wanna know! This astronomy things about Planets, Universe is cool! Thanks...

Answer 1

No. You can't see Uranus or Neptune with the naked eye, and they're much, much bigger.

Answer 2

Well I can't see Pluto with a naked eye so I think you can't see the new planet neither.

Is Pluto a planet?

Answer 3

we can barely see pluto from here even witht he most advanced telescopes, to get a picture in anything even resembling detail, we have to travel quite far first...

so no, you can't see it.

Answer 4

First of all,2003 UB 313 is now called Plutoid.It is not a planet.It is named Eris.

It travels in orbit37Astronomical unit when very near,68AU when far away from Sun. So only when it reaches near sun, it can be seen in telescopes.

By naked eye,Never!

Even Uranus,Neptune,pluto are not visible to naked eye.

Answer 5

I've seen Pluto in my 10 inch reflector.  It's magnitude 13.7.  This scope allows me to see objects to magnitude 15 - under ideal conditions.  Pluto is never very high in the sky from my spot on Earth, and so is never optimal. Pluto is about the dimmest i can do. Eris is five magnitudes dimmer, which will require about 100 times more light gathering.  The square root of 100 is 10, you you'll need a telescope about 10 times the diameter of my 10".  That would be a 100 inch telescope - that's 2.54 meters.  What a scope! Very expensive. The easier way is to use astrophotography.  A fairly short exposure will get you to magnitude 18.7 with a modest telescope on a tracking drive.  And, you can take a picture a few nights later and verify that it moved.

Answer 6

no you can't

Answer 7

Sorry, not a chance.  Eris (current name for 2003 UB313) is considered a "dwarf planet" that orbits the Sun at distance roughly equal to three times that of Pluto, which also cannot be seen by the naked eye on Earth.  Eris orbits the sun once every 557 Earth years.

Answer 8

The only planets that can be seen with the naked eye are Mercury, Venus, Mars, Jupiter and Saturn.

Consequently none of these planets was ever "discovered" because man has always been able to see them.

Uranus (which was almost called George) was the first planet to be discovered, and it required a telescope.

The dwarf planets out near Pluto all need a telescope to be seen...
