Find a place with a clear view of the sky, such as a field or a park. Jupiter and Saturn are bright enough to be seen from most cities. Look to the southwest sky one hour after sunset. Jupiter will appear like a brilliant star and will be plainly visible. Saturn will also be easy to see, though it will be slightly lower in the sky than Jupiter.
Jupiter is the fifth planet from our Sun and has been known to humans since antiquity. It is important in astronomy because it is the largest planet in the Solar System and thus plays an integral role in determining how other planets are sized compared to Earth. Astronomers use Jupiter's size as a reference for other planets when discussing their relative sizes. For example, Venus and Mars both seem small when compared to Jupiter but in fact, they are larger than Jupiter.
Jupiter is named after the Roman god of gods and king of planets. It is a gas giant that orbits around the Sun every 12 years at a distance of 584 million km (360 million miles).
The brightest object in the night sky, Jupiter is also very large and emits powerful radiation into space. The aurora on Jupiter's poles are made up of gases that stream out into space when the planet rotates under them, forming clouds that glow in different colors.
Jupiter was first spotted by Galileo Galilei using a telescope in 1610.
Find a site with an unobstructed view of the sky, such as a field or park, to observe the Great Conjunction. Saturn will be slightly smaller than Jupiter but still easy to see.
Jupiter is the fifth planet from our sun and the largest planet in the solar system. It has been described as an "icy world" because it contains many large ice-covered regions called 'lakes'. Although mostly made up of hydrogen and helium, there is also water vapor trapped under the ice that forms lakes and oceans. The other three members of the Solar System: Mercury, Venus and Mars. All four planets orbit around the center of the Sun; however, each takes a different amount of time to complete an orbit. These differences in distance from the Sun cause each planet to have a unique climate.
Saturn is the sixth planet from the sun and the second largest planet in the solar system. Like Jupiter, it has many large moons that contribute to its great beauty. In addition, clouds of gas and dust swirl within Saturn's atmosphere creating some of the most stunning photos from space. NASA's Cassini spacecraft discovered that there was organic material on Saturn's moon Enceladus which could provide the ingredients for life beyond Earth.
Jupiter's four huge moons can be visible with the naked eye, but if you have binoculars or a small telescope, you might be able to see them. The great astronomer William Herschel first saw them all in 1784, using a telescope made from a wine bottle.
The planet Jupiter is about 12 times wider than Earth. It has two large moons, Ganymede and Io. Ganymede is the most massive moon in the solar system at 2% of Jupiter's mass. Io is less than one-fifth as massive but has a surface that changes rapidly due to volcanic activity.
Io has 20–60 km deep cracks called valles that may be channels for lava flows or perhaps frozen methane below -300°C. These images were taken by NASA's Galileo spacecraft during its close flybys of Jupiter in 1995 and 1996.
Galileo also discovered a new moon orbiting Jupiter named Metis. This image was taken by the Galileo spacecraft on February 7, 1997, at a distance of about 545,000 km from Jupiter.
Metis is an asteroid that was once part of a larger body that got torn apart by Jupiter's gravity. The pieces are now trapped within Jupiter's orbit.
Jupiter is best viewed in the hours following sunset. As the sun sets, visibility increases. After-sunset view Saturn is best visible in the hours following sunset. Bring binoculars after sunset and for the duration of the night. Don't forget your camera!
Jupiter is the largest planet in our solar system and can be seen with the naked eye from anywhere on Earth if it's night. It can also be seen as a bright starlike object during the day, but it's usually too far away from us to be recognizable as a distinct object.
From space, Jupiter is a great example of a world that more closely resembles a gas planet than a solid one. It has four large moons, but only two of them are large enough to be considered significant sources of gravity: Io and Ganymede. The other two are Callisto and Europa. All together they account for less than 1% of Jupiter's mass. The rest is made up of hydrogen and helium gases.
On Earth, we have oceans covering 71% of our planet's surface. But even though Jupiter has more massive clouds than Earth, they cover only 4% of its surface. The other 96% is made up of hydrogen and helium gases.
The best times to see Jupiter with the naked eye vary depending on where you live.
Take a look at the appropriate portion of the sky.
Jupiter and Saturn are brilliant enough to be seen in locations with clear sky and no cloud cover, as well as from most cities. This also implies that the incident is visible with the naked eye. According to the statement, spectators with binoculars or a small telescope may be able to glimpse Jupiter's four big moons.
Jupiter is the largest planet and has been known since ancient times. It takes 12 years to perform one orbit around the Sun, while Earth makes one complete rotation in 24 hours. Because of this difference in speed, astronomers call Jupiter's day a "day" and its year "an Earth year".
Saturn is the second-largest planet and was also known to ancient peoples. It takes 30 years to perform one orbit around the Sun. Like Jupiter, Saturn has 4 large moons: Titan, Uranus, Neptune and 17th moon Pluto.
Titan is the only moon that shares its orbit with another planet, namely Uranus. The other three are completely alone in space. Astronomers know these 3 bodies through their gravitational fields, which are stronger than those of the other planets.
Neptune is the furthest planet from the Sun and lies within the orbit of Uranus. It takes 2 days for Neptune to make one full orbit around the Sun. It is also the only gas giant among these 5 planets.
