Yes. Mercury is much closer to the Sun, making it harder to see. It also orbits the Sun more often than Jupiter, so it is often on the other side of it. Jupiter can be seen for months at a time when it is visible.
Most comets can be seen before sunrise because they are visible in the early morning sky when the sky is still dark. This is because they are most visible against the darker sky background. Additionally, comets that are visible in the nighttime sky are also best seen in the few hours before sunrise, when the sky is darkest.
Venus is the brightest light in the sky except for the Sun and moon when it is out. Also, Mars, Jupiter and Saturn are readily visible in the night sky. Mercury is visible, but only right before sunrise or after sunset.
Mercury was discovered in antiquity and has been known to humans since at least 3000 BC. It has been observed for thousands of years as it is visible to the naked eye in the sky.
On 30th July 2017 the bright planet near the Moon just after sunset is Jupiter. Mercury is also visible in the lower part of the sky.
No, the moon comes out at a much earlier time then when the sky turns dark. This is due to the orbit of the moon. The moon is visible in the sky during the day. So, no the sky does not turn absolutely dark when the moon comes out. If it did, then we would have extremely long nights.
No. Mercury lies very close to the sun, and 'follows' the sun across the sky very closely. Therefore it is usually only seen right before dawn or just after sunset.
Yes. Mercury is much closer to the Sun, making it harder to see. It also orbits the Sun more often than Jupiter, so it is often on the other side of it. Jupiter can be seen for months at a time when it is visible.
A dark line in the sky visible from the ground could be caused by a phenomenon like a solar eclipse, a passing storm cloud, or pollution in the atmosphere blocking sunlight.
Is visible in our sky
No. There are visible six objects in the sky that are not stars: the moon and the five planets Mercury, Venus, Mars, Jupiter, and Saturn.
Mercury does have a sky.
Most comets can be seen before sunrise because they are visible in the early morning sky when the sky is still dark. This is because they are most visible against the darker sky background.

Venus is the brightest light in the sky except for the Sun and moon when it is out. Also, Mars, Jupiter and Saturn are readily visible in the night sky. Mercury is visible, but only right before sunrise or after sunset.
Stars are visible at night because the Sun has set, creating a dark sky that allows the stars' light to be visible. When it is dark enough, our eyes can adjust to the lower light levels and perceive the light emitted by distant stars in the night sky.
Mercury was discovered in antiquity and has been known to humans since at least 3000 BC. It has been observed for thousands of years as it is visible to the naked eye in the sky.
Earth and Venus. From Earth Venus and Mercury are planets visible as "morning" and "evening" stars. From Venus, Mercury would appear in the morning and evening sky. From Mars I would expect Earth, Venus, and Mercury to all be morning and evening "stars."
