When will the five most visible planets 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.
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.
Can you see planets with the naked eye?
Yes, you can see some planets like Venus, Mars, Jupiter, and Saturn with the naked eye as they are bright enough to be visible in the night sky. They appear as bright, non-twinkling dots of light among the stars.
What are visible objects in the sky?
Visible objects in the sky include the Sun, Moon, stars, planets, satellites, meteors, and the International Space Station (ISS). Telescopes or binoculars can make some objects like planets and clusters of stars easier to see.
How are moon and planets are visible even if they are not luminous?
For the same reason that a rock is visible even though the rock is not luminous.Some source of light, such as a flashlight, illuminates the rock, and some of thelight from the flashlight bounces off of the rock in just the right direction to enteryour eye.Similarly, in our neighborhood, some source of light, such as a flashlight, illuminatesthe moon and the planets, and some of the light from the flashlight bounces offof the moon and planets in just the right direction to enter our eyes.The Sun is that source of light.
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.
Which planets are visible in August?
There are five planets that are generally visible to the naked eye.In September 2009, Mercury and Saturn are too close to the Sun to be seen.Jupiter rises just before sunset, and is visible most of the night.Venus and Mars rise a couple of hours before dawn, and are easily visible in the eastern sky before the Sun rises. Venus is the incredibly bright one, and Mars has a distinct reddish tint, so they're both fairly easy to pick out.
How are other planets compared with earth?
some planets are bigger and some are smaller. some have different atmospheres. some of the planets are almost pure gas. some planets have as much as like 60 moons while ours only has one
Why some planet have rings some do not?
Actually all planets in our Solar System have a ring system. Most are much to faint to discern with the visible eye, but they are there.
What have telescopes discovered and found out?
Telescopes have helped discover many things in space that are not visible such as some of the outer planets of our solar system.
When the sun is out why is the moon an the stars stilll out?
Stars and Moon are always there; only that sometimes, in the daytime, they are outshone by the Sun. However, the Moon, and some of the brighter planets (especially Venus), are visible even at noon (if you know exactly where to look).
