When a comet passes near the sun the sunlight vaporizes ice on the surface, forming a cloud of gas ad dust that is swept away from the sun by the solar wind. The gas and dust reflect a lot of sunlight, making the comet visible for millions of miles.

Are there currently any visible comets in your solar system?

There are no visible comets at this time.


What source of light makes comets visible?

Comets are visible because they reflect sunlight. As a comet travels closer to the Sun, the sunlight heats up the comet's surface, causing it to release gas and dust that form a glowing coma and tail. This reflected sunlight is what makes comets visible from Earth.


How many comets are seen in 30 years?

There is no set number, because new comets are discovered all the time. Not all comets that are discovered will be visible with the naked eye.


What other comets will be visible from earth by 2100?

It is challenging to predict which comets will be visible from Earth by 2100, as new comets are discovered regularly. However, some of the periodic comets that are expected to return within this timeframe include Comet Halley (2061), Comet Hale-Bopp (c. 4385), and Comet Swift-Tuttle (2126).


How quickly to comets cross your skies?

Comets can actually be visible in the sky for up to a few hours, depending on how close they actually get to Earth.


Are most comets seen before sunset or sunrise?

Most comets can be seen before sunrise because they are visible in the early morning sky when the sky is still dark. This is because they are most visible against the darker sky background. Additionally, comets that are visible in the nighttime sky are also best seen in the few hours before sunrise, when the sky is darkest.


Most comets are found before the sunrise or the sunset?

Comets are typically observed before sunrise or after sunset when the sky is dark enough to see their faint tails against the backdrop of space. This is because comets are most visible at these times when they are illuminated by the sun but not obscured by the brightness of daylight.


What comets have been seen in the daytime?

Generally, only the brightest comets are visible in the daytime. There was a very bright comet in 1911, which preceded the appearance of Halley's Comet that year. Hale-Bopp was briefly visible during the day, as well.


Is comet visible in the sky?

As of October 12, 2014 there are no comets visible to the naked eye from Earth. There are several visible to telescopes, and a couple that are visible in binoculars, if you know where to look. A good website to go to if you want to know about currently visible comets is cometchasing.skyhound.com. The site is updated with names, approximate positions, and brightness; they even give some idea of what it will take (in terms of how large a telescope you need) to see it. Once you know the names of the comets that might be visible, you can check for further information on them so that you know exactly where to look on any given night.


Are comets visible for most of their trip?

Will there be any comets visible tonight?

Comets tend to be visible for weeks or even months. They don't suddenly appear and then vanish again in a single night. So if there's been a comet visible recently, then it will probably be visible tonight; if there hasn't, there probably won't.There is some point, of course, at which a comet that was not previously visible becomes visible, and at which a comet that has been visible vanishes again. But what almost never happens is that a brilliant, spectacular comet appears overnight.There are nearly always a few comets visible through sufficiently powerful telescopes. The Related Links will take you to the Comet Chasing website, which lists all known comets currently theoretically visible to amateur astronomers (that is, you don't need a billion-dollar telescope to see them, though you may need a scope costing several thousand dollars to do so).


If earth had no atmosphere would comets still be visible from its surface?

Yes. Comets do not enter the atmosphere of the earth (we hope!). What you see is gasses that are released from the comet, illuminated by the sun. However, a meteor (shooting star) is visible only due to the atmosphere heating the meteor.
