The planet Mercury can never be in the sky at your local midnight. Mercury's orbit is so small that as seen from the earth, it's always near the sun. So if the sun has been down for a while, then Mercury also must be down. Venus can be seen later (or earlier) than Mercury, but it's still inside the Earth's orbit and therefore can't be seen at midnight either.
None. planets travel along the ecliptic, which is nowhere near the little dipper.
The constellations of the zodiac fall on the plane of the ecliptic (the plane in which the Earth orbits the Sun) and all the Sun's planets orbit also in the plane of the ecliptic. This means that ALL the planets eventually move through ALL the zodiacal constellations (as seen from Earth). It also therefore follows that the planets are never seen in the non zodiacal constellations.
Planets can be seen from Earth because they reflect sunlight, making them visible in the night sky. The planets in our solar system are relatively close to Earth, which allows them to be seen without a telescope or binoculars. Their brightness and position change as they move along their orbits around the Sun.
Planets can be seen because they reflect sunlight. As light from the Sun hits the planets' surfaces, some of it is absorbed, and the rest is reflected back towards us on Earth, making them visible in the night sky.
The five outer planets are the ones with bigger orbits than the Earth, which are Mars and the four giant planets. The outer planets can be seen at their brightest at midnight, when they are at opposition. That never happens for the inner planets Mercury and Venus.
The number of planets never seen could be millions, billions, or trillions. We just have never seen them.
Inner planets orbit inside the orbit of the Earth, can only be seen in the morning or evening sky and are never seen as full disks form the Earth. Outer planets orbit further out than the orbit of Earth and can be seen from time to time as full disks in 'opposition' or overhead at midnight.
No, Venus is best seen at its greatest elongation, when it appears highest in the sky after sunset or before sunrise. At opposition, Venus is on the opposite side of the Sun and is not as easily visible.
That is sometimes what the Moon is called. Seen from Venus the Earth and Moon would be seen as a pair of bright planets up to 0.5 degrees apart at opposition, which is the diameter of the Moon as seen from Earth.
Both Venus & Mercury.
Both Venus & Mercury.
In 37 years of bankruptcy practice, i have never seen a "No Opposition Order." If no opposition to any motion is filed, after the time allowed for such oppositions, the court issues an order allowing the motion, stating that no opposition was filed.
It depends where you are. Some planets can be seen overhead at different times at latitudes up to about 24 or 25 degrees, but at higher latitudes they are never overhead. They are highest in the sky at midnight in the winter. At that time they are passing through the constellations of Taurus and Gemini when seen from the northern hemisphere, or Ophiuchus and Sagittarius from the southern hemisphere. That applies to all eight planets.

The planet Mercury can never be in the sky at your local midnight. Mercury's orbit is so small that as seen from the earth, it's always near the sun.

Planets and moons can be seen because of the light that shines off of them in space.
