Yes, Mercury is seen without a telescope since it is one of the five brightest planets. Mercury, on the other hand, is one of the five brightest planets and one of the most hardest to view. Mercury is the nearest planet to the Sun, and only from a few angles can Earthlings see it without interference from the Sun's light. It takes over 12 hours for Mercury to orbit the Sun, so it never gets closer than about 46 million km (29 million miles) from our star. Because it is so close to the Sun, only the very faraway craters are visible from Earth.
Modern telescopes have revealed much about Mercury's nature. Scientists know that there is water under its surface, because probes have found evidence of liquid trapped in deep craters during certain periods of Mercury's history. They also know that there must be ice near the planet's north pole, because infrared sensors have detected excess heat coming from that direction.
These findings were made possible by advances in technology that allow us to look deeply into space, including telescopes and probes sent by humans who wanted to learn more about our solar system. Modern telescopes have also shown that Mercury has many features we would not expect from a planet that is constantly heated by the Sun. For example, it has two large volcanoes that are still active today. These discoveries have come from studies using both ground-based telescopes and those sent into orbit by astronauts aboard spacecraft.
Yes, Jupiter is seen without a telescope since it is one of the five brightest planets. Jupiter emits a tremendously brilliant white light, shining brighter than any other star in the sky. Since Jupiter is so far away from Earth, its appearance does not change from night to night.
Jupiter is always visible to the naked eye, as long as it's night where you are. It's one of the stars that never sets!
Jupiter is the largest planet in our solar system and also the most massive. It lies about 584 million miles from the sun. It has an average diameter of 1303 miles which makes it larger than all but the smallest stars. However, like all other planets, it is mostly made up of empty space. There is some water vapor and organic material floating around in Jupiter's atmosphere, but no evidence of life whatsoever.
Jupiter was originally thought to be the only planet outside of our own to have active volcanoes. Scientists believed that Jupiter got its energy from the decay of radioactive elements within its body. In 1980 this theory was proved wrong when another group of scientists discovered that Venus has active volcanoes too. Since then, Jupiter has become known as a "cool" planet.
It takes Jupiter about 12 years to complete one rotation on its axis.
Is it possible to see Saturn without a telescope? Yes, Saturn is seen without a telescope since it is one of the five brightest planets. Without any additional viewing equipment, Saturn will appear as a brilliant star in the sky. Its apparent magnitude is 1, so it should be visible with the naked eye under ideal conditions. However, like all other stars, Saturn is not visible alone; you will need to know where in the sky to look.
Where can I see Saturn with the naked eye? If you are lucky enough to live near a large body of water, you can see Saturn and its moons with the naked eye from shore or from a boat. In fact, this is how they were first discovered by astronomers. The first astronomer to see Saturn's rings was Thomas Jefferson, who did so in 1789 from his home in Virginia. He described them as being "like those on Jupiter but much finer."
Saturn is not only the largest planet but also the most massive one too. It has a diameter of 401 miles and a mass about 590 million km^3. Earth's mass is 5.9 billion km^3. So Saturn is more than twice as massive as Earth but less than three times as dense.
The majority of the planets in the solar system are visible with the naked eye, with just Neptune and Uranus eluding unaided observers. However, the five "bright" planets, Mercury, Venus, Mars, Jupiter, and Saturn, seldom share the night sky at the same time. From Earth they appear as bright points of light (with the exception of Jupiter's pale orange hue), but from other places within their orbits they can be seen during certain times of the year when they lie along the horizon or beyond it.
Mercury is the inner planet and lies between the Sun and the Earth. It takes 88 days to orbit the Sun, which is why Mercury is called an "erratic" planet. Because it appears dimly lit from Earth, astronomers have found many ways to observe and study it over the years. One method used its orbital distance to estimate the size of Earth! A second way to determine size is to look at how much radiation it receives from the Sun. Radiation shields such as ozone and Earth's atmosphere protect us on Earth, but not on Mercury where temperatures can reach 450 degrees Fahrenheit (232 degrees Celsius). The pressure of this heat causes mercury to liquefy at some points below 45 degrees N latitude, forming a global ocean that has perhaps dried out by now since Mercury has only been observed in extreme conditions.
Venus is the next planet out from the Sun.
Mercury is our solar system's nearest planet to the Sun. It is only seen in the early morning, soon after dawn, or after sunset since it is so near to the sun. In fact, ancient Greek astronomers once thought Mercury was two distinct objects. They called the bright object "Phoebus" after its Roman name.
Today, we know that Mercury is a very small, rocky planet with no appreciable atmosphere. It orbits the Sun every 87 days at a mean distance of 40 million km (25 million miles).
The reason ancient Greeks saw two objects when observing Mercury is because they were seeing both Phoebus and Hesiodus - one being a direct view of Phoebus, the other being an evening view of Hesiodus from four months later.
Hesiodus was the name given to Mercury by ancient Greek poets including Homer. They said he was the son of Jupiter, sent to watch over men and tell them what will happen next year. From this explanation comes the term "Hesiodic poetry", which is any poetry written about the Trojan War and its aftermath.
Phoebus was the name given to Apollo by ancient Greeks. They said he was the god of light and prophecy and had golden hair and wings. He was also known as the "Sun-god".
Because Venus is generally one of the brightest objects in the night sky, it may be viewed without a telescope. The planet will appear to the naked eye as a brilliant star, although less twinkly. It's estimated that if you lived somewhere near enough to see this happen, then you would need to go outside around midnight to watch.
In fact, records exist of people seeing Venus as far back as 774 AD! But these sightings are not reliable - they were probably only recorded when there was no cloud cover over its surface.
Today, people live all over the world, so it's likely that someone else has already seen Venus during nighttime hours. If you want to see what everyone is talking about though, then get out at midnight when it's dark everywhere except for where you are.
And don't forget your camera!
Venus is always visible in the evening twilight, and can often be spotted before or after sunset. It's also one of the few planets that can be seen with the unaided eye, especially when it's high in the sky. So start looking up at night!
