A light year is a unit of space, not time. It is the distance light travels in a year. Eris is far less than a light year away.
no it's a dwarf planet I would think that it is a dwarf planet, but its moon, Sharon, is nearly as big as it, so some MAY argue that Sharon is a dwarf planet and Pluto is the moon, but considering Pluto is slightly bigger than Sharon, I would think that Sharon would orbit Pluto rather than Pluto orbiting Sharon.
Yes and no. It was decided on August 24, 2006 that Pluto be classified a dwarf planet. Because dwarf planets are a subclassification of planet, it would be accurate to call Pluto a planet, in a general setting (bearing in mind, though, that there are 10+ other dwarf planets in our solar system, some larger than Pluto).
Neptune and Uranus. It would be Pluto and Neptune but pluto is no longer a planet it is a dwarf planet
One light year is around 10 trillion km or 6 trillion miles. Nine lightyears would be 90 trillion km or 54 trillion miles. You would generally just say nine lightyears though.
Under the current definition of a planet, yes it can! If a gas giant were to share its orbit with other objects of significant mass (other than moons, comets or asteroids), it would definitely qualify as a dwarf planet. In order to be a planet, it would have to "clear the neighborhood" until it was the dominate influence in its orbit.
If a dwarf star crashed into a planet,the planet would likely explode.
A black dwarf is not a planet; it is the remnant of a long dead star that has cooled. A black dwarf would range from about 7,000 to 17,000 miles in diameter.
It is giant. If it was small, it would be a dwarf planet instead of a planet.
Neptune. It would be Pluto, but Pluto is a dwarf planet ( a planet that was a planet, but decided that it wasn't a planet)
It isn't a planet. It doesn't exist in the solar system anymore. As a dwarf planet, but not as a proper planet.
the farthest planet away from our sun would be Pluto, but since Pluto is counted as a dwarf planet, Neptune would be the furvest planet away

Neptune. (Pluto is no longer considered a planet, but, rather, a dwarf planet.)
In order to be classified as a dwarf planet, an object has to be large enough to have achieved hydrostatic equilibrium - that is, forced by gravity into a roughly spherical shape, unlike the odd shapes of asteroids. The lower limit to the size or mass of a dwarf planet is thus much more a matter of observation than formal definition. The size would thus depend upon its mass, the lower limit of which would be dictated by properties of matter. To be considered a proper dwarf planet it would also need to be in solar orbit and not, for example, a moon of another planet; it would further not have cleared the neighborhood around its orbit, as, for example, Pluto has not.
The common noun would be "dwarf planet."

A black dwarf would be about the same size as a terrestrial planet such as Earth, so it would be larger than some planets but smaller than others.
