orbital periods and positions relative to Earth and the Sun. As they travel along their respective orbits, their visibility changes throughout the night and from night to night, depending on their alignment. Additionally, some planets may rise and set at different times, making it impossible to see all of them simultaneously. Consequently, the naked-eye visibility of planets is influenced by their unique orbits and the Earth's rotation.
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 five most visible planets (Mercury, Venus, Mars, Jupiter, Saturn) can often be seen at different times of the year depending on their positions in their orbits. However, there are times when some or all of these planets are visible together in the predawn or post sunset sky. Consulting a stargazing app or website can help you identify when and where to look for them in the night sky.
Generally true, planets don't emit their own light, but are visible largely because of reflected light, the illumination provided by their star, in the case of our solar system, by the Sun. Some planets might produce trivial amounts of light by other means, for example from lightning, volcanism, mineral fluorescence, etc.
They are both visible and inside the solar system.
We can see planets in the solar system because they reflect sunlight, making them visible from Earth. Due to their size and proximity to the Sun, planets appear as bright points of light in the night sky. Telescopes also help magnify and clarify our view of planets.
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.
Mercury
The planets most certainly ARE visible in the northern hemisphere.

Yes, planets do change position during each season. The position of planets changes due to the Earth's orbit around the Sun, causing different planets to be visible at different times of the year. The change in position of planets varies depending on the planet and the season.
the naked eye determines if it is visible.
The five planets visible to the unaided eye are Mercury, Venus, Mars, Jupiter, and Saturn. These planets are typically visible at different times of the year and can be easily spotted in the night sky without the need for a telescope.
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 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.
