Comets

Halley's comet - which returns to our solar system approximately every 75 years - is one example, named after it's discoverer Edmund Halley. Another notable example is Shoemaker-Levy 9. It was observed orbiting the planet Jupiter, but the orbit was decaying - leading to the prediction that it was to crash into Jupiter's surface.

Halley's Comet was observed and recorded many times in many places around the world. Sir Edmond Halley demonstrated that the repeated sightings were of the same object, the comet that now bears his name.

Comets get brighter the closer they get to the sun for two reasons: the sunlight is brighter closer to the sun than it is further away and the comet heats up closer to the sun causing outgassing and the formation of a large coma composed of dust particles and gas around the comet itself giving a much larger area for sunlight to reflect off of.

That sounds like the description of a comet. However, please note that comets ONLY have a tail when they are close to the Sun. During most of their orbit, they are too far away from the Sun to have a tail.

-- There are either eight or nine known planets in our solar system,

depending on what category you like to include Pluto in.

-- Several hundred planets, or evidence of them, have been found in orbit

around other stars, and more are constantly being documented.

It's definitely looking like planet formation around most stars is common in

the universe. It's so devilishly difficult to detect them, though, that there's

no way we'll ever have anywhere near a complete count.

Two things:

1. Comet tails do not follow along behind the comet. Comet tails always point away from the Sun.

2. Comets are not rocky, they are icy.

carbines are triatomic modifications of cabon mainly found in space and comets

Halley's Comet last appeared in 1986. It is the most famous comet and its period of orbit around the sun is approximately 76 years.

That depends on the table.

Why do comets have tails

The meteor is in the atmosphere and is only visible for seconds to minutes.

The comet is much further away outside the atmosphere and can be observed for weeks to many months.

Halley's comet was so far out in space it didn't just pass England, but the earth. And it took several weeks to do so, in November 1982.

No one cares.

A comet is comprised mostly of ice. The tail of the comet is caused by cosmic winds, from our sun, blasting particles off the comet's surface, the tail does NOT point in the opposite direction of travel, as one might expect, but points directly away from the source of the solar winds. That's why a comets tail, (from our perspective) may be traveling in a certain direction but have it's tail pointing in the SAME direction.

I believe it depends on where you sending it and the distance. If you use some private service , mail travels quite fast. For example US - Europe is about 4 working days. Withing the continent much faster. For other destinations eg. US - Australia it could take 1 week. All these estimates are valid for private services, where the cost is larger. For regular post-offices it could take from 1 till 4 weeks, always depending on distance.

It is unknown exactly how long Comet ISON had been orbiting the sun since its discovery in September 2012. However, experts estimate its orbital period is somewhere around 400,000 years, with an immensely-large hyperbolic pathway. As the comet neared perihelion, it disintegrated from its close proximity to the sun between December 2013 and February 2014.

They both revolve around the sun and they are both smaller than planets or moon.

As a comet nears the sun, solar radiation and solar wind cause the comet's icy nucleus to sublimate, releasing gas and dust into space. This forms a glowing coma around the nucleus, which can get pushed back by the solar wind to form a long tail that points away from the sun.

Detailed research on comets indicates that they cannot be older than 4.6 billion years, which is roughly the age of the Solar System. This is because comets are composed of volatile materials that would have sublimated or depleted over long periods of time. Therefore, the age of comets serves as a valuable indicator of the age of the Solar System.

No. The tail of the comet points away from the sun.

There is no such thing. If people in the Philippines practice any REAL science, the explanation will basically the same as the explanation given by real scientists in other parts of the world.
