Dwarf Planets

The planet with two moons is Mars. The moons are called Phobos and Deimos.

400 Octillion Joules. (400,000,000,000,000,000,000,000,000,000)

It's not really a fair question, however.

The Death Star, as depicted in the Star Wars movies, is grossly overpowered for its purpose. It would take a tiny fraction of that energy to simply vaporize the surface and wipe out all life.

Okay, I admit I did not actually calculate the energy required to vaporize a planet. I simply assumed that the energy output of a Sun like star would be sufficient if it were all turned on puny little Alderaan (or Earth).

The Sun outputs 400 Octillion Joules / second.

I dont know if it was a dwarf siren because it was rather large ,but the owner of the light house landing resort and marina in grand rivers,kentucky photographed a grey herin ingulf a siren that looks to me to be at least 4ft long,could u imagine being witness? swallowed it hole...sweet

The name of the third dwarf planet is spelled "Makemake."

Ceres, discovered Jan. 1, 1801 by Piazzi. He and other astronomers were looking for the "missing" planet that "ought" to exist between the orbits of Mars and Jupiter. Ceres is about 900 km in diameter.

If you compare it to Earth and Earth is 1 for mass, Pluto is 0.002.

1.3057×1022 kg

2.8770×1022 pounds

The seven dwarfs are:

Bashful

Doc

Dopey

Grumpy

Happy

Sleepy

Sneezy

Anyone else is not one of the seven dwarfs.

No. Jupiter is not a dwarf planet. Pluto, Ceres, Eris, Makemake, Hauma are dwarf planets.

No. Pluto is a dwarf planet, not a star, and is not visible to the naked eye.

As of January, 2009, there are 5 dwarf planets, and only the asteroid Ceres is close enough to the Sun (just past Mars) to get appreciable solar heating. Surrounded by the vacuum of space, the "hottest" its surface gets is about -34°C.

It has much weaker gravity.

A dwarf planet is not considered a planet because it does not dominate its orbital path and cannot clear that path of debris.

No. It is considered as a dwarf planet If you order a small Pepsi, you still get Pepsi, right? Pluto is a planet. It is a special class of planet; it is a dwarf planet. What it is not is a major planet.

Pluto is the smallest of all known Planets. Now it is considered to be a "dwarf planet". It takes 248 years to make one orbit around the sun.

As to where it is, depends on time. Earth and Pluto move in different orbits, so to detect where Pluto is, requires an exact time.

Eris is a dwarf planet, because it is sufficiently massive that it's formed into a spheroid due to its own gravity, but it has not cleared its orbital path, as it would need to in order to be considered a planet.

Eris is the largest known object in the Kuiper Belt.

Mercury has a diameter of 2,439.7 km

Pluto has a diameter of 2,306

So that means that Mercury is a little bigger

No.

A dwarf planet is classified as a celestial body in direct orbit of the sun that is large enough to be controlled by gravitational force rather than mechanical forces but has not cleared its path of orbit from other objects and debris.

Where the planet orbits has nothing to do with planets being classified as dwarves.

It is now widely accepted that Pluto should not be classified as a planet, because more bodies more massive than it were discovered beyond its orbit. Also, it seems that it has characteristics similar to other objects in the Kuiper belt.

The New Horizons spacecraft. It will reach Pluto July 14th 2015.

Generally not, as asteroids generally are not massive enough to make themselves round with their own gravity. The only possible exception is the dwarf planet Ceres, which was classified as an asteroid for much of the time that people knew of it.

You can consider a dwarf planet to be a special case from an asteroid - one that has achieved hydrostatic equilibrium, which basically means that it has enough gravity to force it into a round shape.
