Which comets have visited our solar system?
All the comets that have been seen in history were in the solar system and most still are.
Is Halley's comet part of our solar system?
Yes. The solar system is everything that orbits the sun.
The plantes and other objects that orbit the sun are called constllations or a solar sysrem?
Planets and other objects that orbit the sun are part of a solar system, whereas constellations are patterns of stars as seen from Earth. So, the correct term is a solar system for planets and objects orbiting the sun.
What do we see comets as?
Comets are seen as bright, icy bodies that orbit the Sun. When they get closer to the Sun, they release gas and dust in a glowing coma and often develop a tail that points away from the Sun due to solar wind.
What is is a solar system?
A solar system is a collection of objects that orbit a star or group of stars. In most solar systems, a central star (or stars, like a binary pair for instance) provides the mass to keep the system in place, and also the light and heat for the smaller planets, moons, asteroids, and comets that are orbiting. The Sun together with the group of celestial bodies that are held by its attraction and revolve around it, or a group of celestial bodies revolving around any star.The solar system is our planets, revolving around a solar power (sun). We kind of depend on each other.The sun and everything that orbits it ( asteriods , planets , comets , etc. )It is the biggest system which comprises of planets revolving and rotating in their orbit, where sun is at the center n other planets like Mercury, Venus, Earth, Mars etc, rotates around sun in an elliptical orbit. Till date there is only one solar system known n seen, but it is estimated that there would be many such solar system in whole universe.!!
Has anyone seen or measured the Oort cloud?
No. However, we're relatively sure that there is a cloud of dust, rocks, gas and ice left over from the formation of our system, far from the Sun. And we have seen comets come in from very distant orbits and then return to the depths of space, and by measuring their orbits we know that most of them are part of our solar system. (There is a class of "parabolic" comets that have wandered in from outside the solar system and which will escape our system to deep space, never to return.)
In what ways are comets and asteroids similar?
Asteroids and comets have a few things in common. They are both celestial bodies orbiting our Sun, and they both can have unusual orbits, sometimes straying close to Earth or the other planets. They are both "leftovers" - made from materials from the formation of our Solar System 4.5 billion years ago. While asteroids consist of metals and rocky material, comets are made up of ice, dust, rocky materials and organic compounds. When comets get closer to the Sun, they lose material with each orbit because some of their ice melts and vaporizes. Asteroids typically remain solid, even when near the Sun. When comets approach the Sun, some of their ices melt. This causes another notable difference between asteroids and comets: comets have "tails" while asteroids generally don't. When the ices in comets begin to melt and other materials vaporize from the heat from the Sun, this forms a glowing halo that extends outward from the comet as it sails through space. There is a big difference when it comes to numbers… although there is a caveat in that we don't know precisely how many asteroids OR comets there are in our Solar System, since lots have never been seen. Astronomers have discovered millions of asteroids - some as small as dust particles and others measuring hundreds of kilometers across (width). But as of this writing, astronomers have found only about 4,000 comets. [However, some estimates say there could be one hundred billion comets in the Oort cloud.]
What is the history of comets?
Comets are remnants from the early Solar System, composed of ice, dust, and rock. They have been observed for thousands of years by various cultures and have often been seen as omens or celestial signs. Halley's Comet is one of the most famous comets, known for its periodic appearances every 76 years.
Does a comet go around the sun?
Most comets travel around the Sun in elliptical paths. The time it takes a comet to make a complete orbit is called its period. Some comets have short periods of less than seven years. Others travel in such huge orbits that they pass near the Sun only once in thousands or even millions of years. As of 1995, 878 comets have been catalogued and their orbits at least roughly calculated. Of these 184 are periodic comets (orbital periods less than 200 years); some of the remainder are no doubt periodic as well, but their orbits have not been determined with sufficient accuracy to tell for sure. No comets seem to have approached the Sun from beyond the limits of the solar system. Therefore, all comets seen by astronomers are considered part of the solar system.
Why are comets not seen very often in the night sky?
Comets spend most of their time far from the Sun in the outer solar system and are only visible when they come close enough to the Sun to develop a visible coma and tail. Additionally, their orbits may not bring them close to Earth very often, making them appear infrequently in the night sky.
Which way do the plants in the solar system rotate around the sun?
All planets in our solar system revolve (or orbit) around the Sun in an anticlockwise direction - the same direction that Earth spins (daily rotation) as seen by an observer looking down from above Earth's north pole. Since known plants in the solar system all grow on Earth, they too would be compelled to orbit the Sun in the same direction as Earth.
The amount of time it takes for a comet to complete its orbit?
33 years.
