The best time to see a comet is when it is closest to the Earth. This is because comets are brightest when they are closest to the sun, and they are also more visible when they are not too close to the sun, so that their tails can be seen. The best time to see a comet is typically in the early morning or late evening, when the sky is darkest.
Comets are important because they can provide us with information about the formation of the solar system. They are also beautiful objects to observe, and they can be a source of inspiration and wonder.
