What is terrestrial light?
Terrestrial light refers to the visible light that originates from sources on Earth, such as sunlight, moonlight, and artificial lighting. This term distinguishes Earth-based light from astronomical light sources like stars and planets.
Are planets always visible?
The planets in our solar system are not always visible to an observer on Earth, for various reasons. Daylight reduces the visibility of planets significantly. Mercury and Venus, since they are inside the orbit of Earth (closer to the Sun), could only be seen in favorable conditions near sunset or sunrise and not in the middle of the night (or similar difficulties in solar transit, or other planets in opposition, close to the line of sight to the Sun). They would not be visible if occluded by a celestial body (or specifically if they are below the horizon). Neptune, being too distant, can't be resolved with the naked eye; exoplanets require sophisticated equipment to resolve.
What time of year can you see planets?
There are generally a couple of planets visible every night of the year. Which planets will be visible and when depends on where each of the planets (and the Earth itself) are in their orbits. Here on August 28, 2009, for example, Jupiter rises about sunset and is brightly visible all night. Venus and Mars rise before dawn. Saturn and Mercury are not visible this month, because they are too close to the Sun to be seen.
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.
Can you see other planets when your on Mars?
Yes, other planets would be visible from Mars just like they are from Earth. Mars has a similar night sky to Earth, so you can see planets like Venus, Jupiter, and Saturn, as well as stars and our own moon.

What is visible at night from the earth?
the stars and some of our planets
Why is a planet never visible from earth?
Six planets are visible from Earth without any optical equipment except your eyes.
Why are planets visible?
Planets are visible in the night sky because they reflect sunlight. As they do not emit their own light like stars do, they rely on the Sun's light to make them visible to us here on Earth. The brightness and position of planets change as they orbit the Sun, making them observable at different times throughout the year.
An important visible feature of the Earth's atmosphere that is a significant reflector of sunlight?
Clouds are an important visible feature of Earth's atmosphere that reflect sunlight back into space. Their brightness and coverage impact the Earth's energy balance and overall climate system.
Which planets have been known for longest?
The naked eye visible planets. Mercury, Venus, Earth, Mars, Jupiter and Saturn.
What are the 5 planets visible from earth without a telescope?
The five planets visible from Earth without a telescope are Mercury, Venus, Mars, Jupiter, and Saturn. These planets are often visible to the naked eye and can be seen in the night sky from various locations on Earth at different times throughout the year.
Why are the planets visible enough even though they are not light sources?
-.-.... umm sunlight reflects off the planets and is shot back to earth.

What year did the Greeks find the 5 planets?
The Greeks did not 'find' five planets. The Earth and theother five visible planets have been visible on any clear night for as long as humans have walked the Earth. They were known to any caveman with normal vision, a touch of insomnia, and enough brain cells to be interested in the things he saw in the sky.

All of them are if you have a telescope. If you don't, then Mercury, Venus, Mars, Jupiter and Saturn are visible. Probably. Earth definitely is.
