Yes, because comets are so tiny and dim.
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.
Yes,when they are close enough to Earth and it is clear out.
More do then we think, but many we aren't able to see. Ones like Haley Bop you could see with a good telescope.
Absolutely. You can see comets pretty much anywhere they pass between Venus and Mars, when they are opposite the sun from us. On the day side sunlight obliterates them from view. Hyukatake and Hale-Bopp were two prominent comets within the past twenty years. Beyond Jupiter they are much harder to see, both because there is much less outgassing and because of their relative size. Such comets are typically found only in fairly large telescopes.
Some comets might also be invisible from Earth, we only see the big ones.
asteroids and comets!
Yes, comets are typically most visible when they approach the Sun and Earth, as the heat causes their ice to vaporize, creating a glowing coma and tail. When they are farther away, they may be too dim to see with the naked eye. However, some comets can still be observed from Earth when they are at greater distances, especially with the aid of telescopes.
They are. We generally first see comets as they approach the Sun and become visible; if the comet survives the near approach to the Sun, we can continue to see them as they move away from the Sun. Depending on the comet's orbit as compared to the Earth's, we sometimes can't see the comet very well until after it is already moving away from the Sun. And of course, the first three comets discovered in 2010 were all discovered by satellites watching the Sun - as the comets fell INTO the Sun.
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.
Yes, as long as an asteroid is within visible distance of earth.
read the earth science book you will see why,
