Two Jupiter moons look tiny against the vastness of the gas giant captured in this video from the Cassini spacecraft


Jupiter is the largest planet in our Solar System. The gas giant, sometimes visible as a bright spot in our sky, is about 79 natural satellites that constantly orbit it.

Two of its most important moons, Io and Europa, look really tiny compared to the immensity of the giant.

Like two small spheres, the natural satellites move through the orbit of Jupiter, and scientists continue to wonder if any of these objects could have elements that allow the development of life as we know it.

A video made with data from the Cassini space probe shows the orbital transit of the moons Europa and Io. One of the natural satellites has greater speed than the other, while in the background the colors of Jupiter can be seen, a characteristic that exposes the amount of chemical elements in the gas giant.

The moons Io and Europa by the Cassini probe

In terms of size comparison, our Moon is in the middle of Io and Europa. The first mentioned is larger than our natural satellite, with an extension of 1,821 kilometers (ours has 1,737 km).

While Europe is smaller. The Cassini space probe calculated, at the time, that this satellite of Jupiter has an extension of 1,560 kilometers.

The Cassini space probe was a major project of NASA, ESA and the Italian space agency. It was launched in 1997 and its original mission was to study Saturn. However, since Jupiter was also in its path, it captured data to reveal previously unseen information about the gas giant.

Currently, scientists continue to study and analyze the data that the wonderful space probe took, despite the fact that it entered Saturn and disintegrated on September 15, 2017.
