What Makes Planets Visible?

Are the planets visible to the naked eye? If so, then you have probably wondered what makes them visible. Light pollution makes planets visible to the naked eye yellow and orange, owing to the way they are lit. But do the planets really have that much light to be visible to the naked eye? Let’s find out! This article will help you answer that question! Let’s start with Mercury. Then we’ll discuss Venus, Mars, and Jupiter.


Mercury is one of the nearest planets to the Sun, making it difficult for most people to see. This is because it appears close to the Sun, only about 17 to 28 degrees from the Sun. As a result, the planet can only be observed from Earth through a telescope at low twilight, shortly after sunset or before sunrise. Mercury typically makes three appearances in the morning per year, and is only well-placed for about half of the day in a given location, due to local ecliptic angle and twilight.

The planet Mercury is also very close to the Sun, causing it to appear as if it is “flying” in our skies. The planet’s surface temperature is below two hundred kelvins, which is warmer than Earth’s. Because Mercury is so close to the Sun, this means that the planet’s surface temperature never gets above eight hundred degrees Fahrenheit. This phenomenon is particularly noticeable at noon, when the planet’s temperature reaches 700 kelvins. At night, the opposite is true; the planet’s warm poles never get this hot.

If you’re wondering when to observe a Mercury transit, it’s important to remember that you’ll only be able to see one of these rare events during the next few decades. In fact, you should aim to see them in North, South, and European regions, as well as Africa and the Middle East. Despite the difficulty of observing them, Mercury is one of the best planets to see transits. During the second half of July, a waning moon will visit each of these planets one by one.


The bright planet Venus will be visible from the eastern horizon this month. Venus will be 4 degrees lower than the crescent Moon, rising at about 4 a.m. and remaining in the morning sky through twilight until around 6 a.m. See more information about Venus’s location and motion at NASA’s Solar System Exploration website. Here are a few skywatching tips for viewing the planet:

Observe the brightest planet as it passes through Capricornus a week into March. It will stay in this constellation until April, briefly crossing into Aquarius. In 2021, Venus will be at its highest elongation, rising 15 degrees above the southeast horizon forty minutes before sunrise. The planet will be close to Mars and Saturn. Look up for them in your star chart, which you can find on the planets Jupiter, Saturn, Uranus, and Neptune pages.

The ecliptic plane is a line on the sky that traces the path of the Sun through the zodiacal constellations. It also shows the plane in which Earth orbits the Sun. All the planets orbit the Sun in this plane. That’s why they’re visible from Earth. You can view Venus at various times of the year, but there are certain seasons in which Venus reaches a more favorable position.


The brightest planet is Mars, but the planets are also visible when their orbits are aligned. Because the planets are so far from the sun, they can be seen from Earth only during certain times of day. The best time to observe the planets is during the early morning hours, before sunrise. Observations of these planets can last for several months. For this reason, you should plan a few days of observation and check the sky regularly to avoid getting frustrated.

To observe the planets, you must have binoculars to get the best view of Mars. Generally, you can find it about 45 minutes after sunset. This time will vary with local twilight. You can also use the naked eye to locate the planet. In general, it is easiest to see the planet after sunset, and 45 minutes before sunrise. This can be very useful if you have trouble locating the planet during twilight.

In February, Mars will rise in the sky at 17:40 GMT, joining the waxing crescent Moon. Look south of the Earth’s horizon and you can see Mars rising in a small telescope or binoculars. You can also look for the waxing crescent Moon, but the best time to observe the planet is during opposition. In May, Mars will be in the constellation of Gemini. At that time, it will be visible at a low angle in the evening sky.


The most obvious thing to notice about Jupiter is that it appears to change position against the starry sky. Each planet has different phases when they become visible from Earth. The visibility of each planet depends on the interaction of the light from the sun with the shadows of the planets themselves. The closer the planet is to the sun, the less visible it will be. To observe all the planets, one may need to observe the sky for months at a time.

The crescent Moon makes Jupiter visible to astronomers. A pair of 10×50 binoculars can reveal Jupiter’s tiny disc and the four largest moons. Using a telescope, one can also track the four largest moons, and the dark bands of Jupiter’s atmosphere can be observed with higher magnification. If the magnification is higher than 30x, the planet’s Great Red Spot, which is large enough to swallow Earth, can be seen. This spot has been observed for centuries, and is one of the planets with the highest surface brightness in the whole solar system.

During opposition, Jupiter will be the brightest object in the night sky. Observing Jupiter with a telescope will allow you to see its four Galilean moons, including Ganymede, Io, Europa, and Callisto. These satellites were first discovered by Italian astronomer Galilei in 1610.


The 61 moons of Saturn orbit around their parent planet, but none is as large as Titan. Despite this, a good 8″ telescope can show off the four largest moons: Enceladus, Tethys, and Rhea. Even if the rings of Saturn aren’t quite as spectacular as they will be in August, they still make the planets visible. This is one of the most beautiful planetary displays you’ll ever see, so if you’re planning to spend a day at the observatory, make it a point to visit Saturn and its many moons this month.

The overall appearance of Saturn is hazy and yellow-brown, and the surface is actually a complex web of cloud layers, decorated with small-scale features that change over short time intervals. These variations make Saturn seem blander than Jupiter and more similar to Earth. During 1990, Saturn’s surface was covered with a light-coloured storm system. This system spread across its equator and slowly faded after it was over.

On 2nd, Saturn will appear directly opposite the Sun. From then on, it will rise and set on the same day, making it visible to us all night. The rings of Saturn aren’t visible to the naked eye, but you can catch a glimpse of them if you have a telescope. On the 20th, a waxing gibbous Moon will hang to the lower left of Saturn. On the 21st, Jupiter will appear at its brightest, rivaling only the Moon and Venus.


It is not often that five planets are visible in the morning sky, so observing them now will be a treat. But later this year, all five will be in a more convenient position in the evening. If you plan to watch the planets in January, here are some tips to make them visible. You can also check out the planets as they appear in the evening sky. Here are some other helpful hints.

The outer planets are easiest to see, but they will appear like stars if you do not have a telescope. You will need binoculars or a telescope to observe these planets. Observing them is a very challenging task and may take months. Neptune is the most difficult planet to observe – it is about five times fainter than the dimmest star. It is also best to use a detailed sky chart to help you find the planets.

The planet Neptune rises at sunset and sets at sunrise. It is situated in the constellation Aquarius, meaning that it is opposite the sun. Neptune is visible all night long on Friday, as it will rise and set at local sunset and sunrise times. It reaches its highest point in the night sky at local midnight. Observations made before Voyager were not able to resolve the features of Neptune smaller than one tenth of its diameter. Because it is so far away from Earth, pre-Voyager observations focused on the planet’s size and orbital parameters.
