Occasionally they enter the realm of the inner solar system and become visible .five kilometers is a typical size -- but some are much larger.

When are comets tails present?

When they reach the inner solar system.


Are comets close to the inner or outer part of the solar system?

I scientifically believe that comets are closer to the outer part of the solar system.


Do comets come from inner realms of the solar system?

No. They form in the outer solar system where it is cold enough.


What is the hypothetical sphere around the solar system?

The hypothetical sphere around the solar system is known as the Oort Cloud. It is a region of space theorized to contain icy objects and comets that extends far beyond the orbit of Pluto. The Oort Cloud is thought to be the source of long-period comets that occasionally enter the inner solar system.


What celestial object come from a Oort cloud?

Comets originate from the Oort cloud, a spherical shell of icy bodies at the outer edges of our solar system. These comets can be perturbed and sent into the inner solar system where they become visible as they approach the Sun.


Astronomers think that most comets come from?

They are from extreme outer parts of the solar system (known as "Kuiper belt") and from a huge cloud of comets lying far beyond the orbit of Pluto, completely surrounding the Sun (known as "Oort cloud").


How many comets does Mars have?

There are no comets that orbit the planet Mars. Comets, some, orbit the sun. Mars on the other hand does have two moons, Phobos and Deimos.


Is there any form of water on comets?

Comets contain various types of ice (water and also other frozen liquids or gases) which sublime to vapor when the comet approaches the inner solar system.


How do comets vaporize?

Comets vaporize when they enter the inner solar system and heat from the Sun causes the frozen gases and dust within the comet to sublimate, turning directly from solid to gas. This process creates a glowing coma of gas and dust around the nucleus of the comet, and sometimes a tail as well.


Why do you rarely see comets?

Comets spend the majority of their time in the far reaches of our solar system, where they are not easily visible from Earth. They only become visible when they enter the inner solar system and are illuminated by the Sun, hence their rare appearances. Additionally, many comets have long orbital periods, further contributing to their infrequent sightings.


Are the comets found mostly between venus and mercury?

Comets can be found throughout the solar system, but they typically originate from the Kuiper Belt and Oort Cloud, which are located beyond the orbit of Neptune. While comets can pass through the inner solar system and be visible near Venus and Mercury, they do not originate primarily from that region.


Where are Comets usually found?

Comets can be formed anywhere in space. They are mainly composed of ice and dust, which can be acquired from anywhere in space i.e pieces of chipped planets or random space particle. Hope this was helpful x]
