What else can I help you with?
How were comets observed to prove they were beyond the moon?
Comets have a parallax smaller than the Moon's
Do comets orbit Jupiter?
Yes, some comets have been observed to orbit Jupiter. These comets can either be captured by Jupiter's gravity and become temporary moons, or have their orbits altered by Jupiter's gravitational pull.
Why there is no scientific basis about comet and asteroid?
There is a scientific basis. Asteroids and comets have been direct;y observed and studied.
Where do you find comets?
Comets are typically found in the outer regions of the solar system, beyond the orbit of Neptune. They can be observed from Earth when they come closer to the sun and develop a visible tail due to the solar wind. Astronomers track comets using telescopes and space missions.
What is the distance of comet tails that have been observed to extend?
Some comets have tails reaching 160 million kilometers long.
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.
Have Comets actually been observed striking a planet in your Solar system?
Yes. In addition to several comets crashing into the Sun so far this year, the 1994 impacts of the Shoemaker-Levy 9 comet fragments into Jupiter were quite spectacular.
What are small pieces of rock ice and metal called that break off coliding comets?
No collision between comets has ever been observed. Considering their small size, such collisions are very improbable. And considering that a comet emits no light and most of its orbital revolution takes place in the outer solar system where it cannot be observed, the probability of our observing such a collision is virtually zero.
How often are comets seen?
Comets are typically visible from Earth every few years, with some being more frequently observed than others. Most comets are only visible for a short period of time as they move through the inner solar system. Astronomers actively monitor for new comets using telescopes and observatories.
What comets names start with the letter h?
Two comets that begin with the letter "H" are Comet Halley and Comet Hale-Bopp. Comet Halley is one of the most famous comets known for its periodic return to the inner solar system, while Comet Hale-Bopp was a bright and widely observed comet in 1997.
What evidence do we have that comets are permanent solar system members rather than interlopers from other parts of the galaxy?
The trajectories of all observed comets to date have been elliptical, indicating that they orbit the sun. A comet coming in from outside the solar system would follow a hyperbolic trajectory.
Is there still an idea or information about comets asteroids or meteors that are still unresolved?
Much about what we think we know about comets is, at best, educated guesswork. We have sampled the tails of three comets, and all were different. We observed an impact into the nucleus of one comet. We believe that comets have a source in the "Oort Cloud", but no instrument currently exists that is sensitive enough to detect the Oort Cloud - so we have NO EVIDENCE that the "Oort Cloud" exists. It makes "sense"; comets have to come from SOMEPLACE, since no comet could have survived 4.5 billion years of close passes by the Sun. But the fact is that what we know about comets is like a bucket, and what we do NOT know about comets is like an ocean. And over the next 300 years, I predict that we will discover that at least half of what we "know" about comets will turn out to have been wrong.
