The planets continually move among the stars, causing them to appear in constantly changing
places, in the sky and among the constellations.
Mercury and Venus can never appear in the east at sunset. Since their orbits keep them closer
to the sun than earth's orbit keeps us, there's a limit to how far from the sun they can appear
in our sky.
But each of the so-called "superior" planets ... each one farther from the sun than earth ... can
appear anywhere in our sky at some point during its orbit.

The inner planets Mercury and Venus are not seen at midnight except sometimes in high arctic latitudes.

Which planets are never seen at midnight?
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.
What planets can never be seen at opposition?
Venus and Mercury because they are inferior planets.
How can planets be seen from earth?
They reflect light from the Sun.
What planets can be seen in certain constellations?
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 because?
They reflect the Suns light back to Earth
The A planet that can never be seen from Earth at midnight?
Neither Mercury nor Venus are visible at midnight. Both planets are closer to the Sun than the Earth is.
Which of the planets known to the ancients can never be seen high overhead at midnight?
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.
What planet is an outside planet?
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.
What two planets can you not see from Earth at midnight?
Neptune and Uranus cannot be seen without the aid of a teloscope.

How do you know if a plant is an inner or outer plant?
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.
What is name planets move horezonally?
Planets appear to move horizontally when they are in that part of the ecliptic that lies horizontally across the southern horizon at midnight (seen from the northern hemisphere). That occurs when a planet is at a right-ascension of 18 hours (in Sagittarius), and a couple of hours either side. A snapshot of the planet taken every night at midnight shows it moving horizontally (approximately) from right to left. All planets do this.
Why can planets and moons be seen?
Planets and moons can be seen because of the light that shines off of them in space.
Why are the terrestrial planets knwon as the ancient planets?
they can be seen by the naked eye
Have any planets never been seen in the solar system?
The number of planets never seen could be millions, billions, or trillions. We just have never seen them.
What planets can be seen by a person?
Earth
Planets can be seen in the sky because?
The planets shine because they reflect sunlight.
