Discovered in 1979 by NASA's Voyager 1 spacecraft, Jupiter's rings were a surprise, as they are composed of small, dark particles and are difficult to see except when backlit by the Sun. It is a gas giant with a mass one-thousandth that of the Sun, but two-and-a-half times that of all the other planets in the Solar System combined. It is ten times bigger than the Earth and one-tenth the size of the Sun. This was a historic discovery which altered the course of astronomical science to a great extent.

Jupiter's four largest moons—Io, Europa, Ganymede and Callisto—were first observed by the astronomer Galileo Galilei in 1610 using an early version of the telescope. Jupiter was observed by Galileo Galilei on January 7, 1610. However, when Galileo observed them on a different night, the “fixed stars” had changed positions. It is also one of the planets visible to the human eye. If the telescope will be held steady at Jupiter, the seeker should remain focused for one to two minutes or until the eyes get adjusted to the light. It is usually the third brightest object in the sky, behind the moon and Venus. Having said that, it's worth noting that there is no dearth of sources which stress on the fact that it was discovered by Galileo. Copyright © 2020 LoveToKnow. One of the earliest recorded observations of Jupiter dates back to the fifth century, and can be found in an Indian astronomical text called the Surya Siddhanta. Of course, as with the other classical planets, there were astronomers who observed the movement and status of the planet. It’s an anticyclonic storm, and it’s located close to the equator of the planet. Impressively, Galileo’s estimations were quite close to the actual periods of the moons. It is an enormously huge and compact ball of cloud made up of mostly hydrogen and helium. Jupiter has sixty-three known moons which makes it the Sun’s counterpart in its own mini solar system. When viewed from Earth, Jupiter can be bright enough for its reflected lightto cast visible shadows, and i… There is no single person who is credited with the discovery of Jupiter.

The gravitational field of Jupiter is so strong that the Shoemaker-Levy 9 Comet, which was anticipated to crash into Jupiter, got disintegrated into 20 fragments as soon as it entered it. Impressively, Galileo’s estimations were quite close to the actual periods of the moons.

Side by side, Jupiter can be compared to a basketball while the Earth can be just as small as a dime. The Indian astronomers also observed the planet and wrote the observations in their Surya Siddhanta, credited to astronomer Brahmarishi Mayan.
