How is pluto similar to the other planets?

Answer 1

Most comets do not affect the Earth at all. And as long as it stays a comet, and doesn't become an enormous meteor, they won't.

But back when the solar system was young and the Earth was new, there may not have been much in the way of water or gasses or other volatile compounds on the Earth. Some scientists believe that a succession of comets impacted the Earth and brought ice, water, frozen "gasses", and perhaps even life itself to the Earth.

65 million years ago, a comet or asteroid struck the Earth near what is now the Yucatan Peninsula in Mexico; the impact and its aftereffects killed off the dinosaurs, almost all large animals, and nearly 75% of all life. In the long run, over the next few billion years, several comets will likely collide with the Earth, eliminating or vastly changing the course of life on this planet. Unless, of course, we prevent it.

The meteor that exploded near Chelyabinsk, Russia on February 15, 2013 should be a warning; it WILL happen again, unless we can prevent it.

Answer 2

Unless the comet actually STRIKES the Earth, it has no effect at all.

Actually, that's not entirely true.... For thousands of years, there have been some crazy fools who have done incredibly stupid things when panicked by the sight of a comet in the skies. In 1066, the sight of a comet convinced William the Conqueror that he was fated to be victorious in the coming battle for England, and he was.

In 1997, the sight of Comet Hale-Bopp persuaded Marshall Applewhite and 38 of his followers to commit suicide, convinced that by doing so they would be transported to a UFO that they believed was trailing behind the comet.

But the comet itself has no effect whatsoever to the Earth or lifeforms on it.

Answer 3

In mid-September 2011, the following comets are brighter than magnitude 12

as seen from Earth:

-- P/2007 R5 SOHO

-- C/2010 X1 Elenin

-- 45P Honda-Mrkos-Pajdusakova

-- C/2009 P1 Garradd

Answer 4

An asteroid is a rock orbiting the Sun usually between Mars and Jupiter but some stray into sporadic paths also passing or colliding with the Earth.

A comet is a ball of frozen air and dirt orbiting the Sun in a very large orbit usually taking it far beyond Uranus. When approaching the Sun the mass melts forming a "tail".

Answer 5

First, the term "other planets" is not appropriate, since Pluto is not currently considered a planet.

Pluto has three known moons, but several other asteroids also have moons or equivalent. It also has a very tenuous atmosphere.

Answer 6

There's a web site for tracking comets; I'll put a link in the related links section.

However, as of July 10 2012 (the date of this writing), I don't think there are any comets bright enough to be visible to the naked eye; comets are dimmer (have a lower surface brightness) than their magnitude indicates, and none of those currently listed are anywhere near naked-eye magnitudes. C/2011 L4 has a good possibility of being a naked-eye comet next year, but it's currently still down around 12th magnitude.

Answer 7

Comets are the most distant members of our solar system. Their orbits are highly elliptical, and are many orders of magnitude greater than our planets. Over time, the comet tails are present at every point of their orbit at greater or lesser densities. As Earth's annual orbit around the sun (our star) sweeps through the comets' tails, we hit granules of dust. These particles accelerate through our atmosphere, essentially burning up.

Accordingly, we have seasonally predictable meteor showers, such as the Leonids.

Answer 8

A meteorite is on the Earths surface, a meteor is the th atmoshere (probably burning because of speed and friction and bleh blah bleh) and a meteoroid is just kind of floating in space, so there are 3 stages of pretty much the same thing, only shrinking. the are all made of stone though.

Answer 9

It looks like a star or possibly an asteroid. Obviously it is not a star or asteroid though.

Answer 10

they are all in space and all are round or irregular in shape.~answered by ahmad salama
