We learnt from our basic science and biology classes that Jupiter is the biggest planet among all 9 planets that exist in our solar system. Recently, Pluto has been delisted from the planet bunch in our system as the International Astronomical Unit (IAU), and Pluto is now known as a dwarf planet. A dwarf planet as defined by Wikipedia.

A dwarf planet is a planetary-mass object that is neither a planet nor a natural satellite. That is, it is in direct orbit of a star, and is massive enough for its gravity to compress it into a hydrostatically equilibrious shape (usually a spheroid), but has not cleared the neighbourhood of other material around its orbit. – Wikipedia

So, among the remaining planets of our solar system, Jupiter is by far the biggest, and naturally, interstellar bodies, the smaller bodies, orbit the larger ones this as a result of several factors, one of which gravity. In this post we will look at the moons that orbit Jupiter, due to its massive nature, it exerts a massive magnetic field has a lot of moons orbiting around it. But we are going to focus on just 4 out of the 69 moons that have been confirmed to orbit Jupiter.

Galilean Moons

They are simply known as the top 4 biggest moons that orbit the planet, and they are Callisto, Io, Europa and Ganymede. They were all the Astronomer of ancient times Galileo Galilei, I believe that’s why the moons were named after him. The names of the four satellites are named after the mistresses/lovers of the Greek god Zeus. We will be briefly looking at each and every one of them shortly. Today, we will be looking at two of the moons, and in the next post, I will discuss the other 2 moons of Jupiter.

We will look at the moons that have the possibility of having life on them

Callisto

Known as the second largest moon among all the moons of Jupiter, and also as the 3rd brightest of them, all Callisto got its name from one of Zeus’s lovers. The planet is composed with a fairly balanced of rock and ice. This heavily cratered satellite, in fact, it is the most cratered solar object in our solar system. It is located outside orbital resonance that affects the other Galilean moon, and the planet is known to possess a very thin atmosphere.

The chemical composition of the atmosphere mainly consists of molecular oxygen, as well as carbon dioxide. Recent studies suggests that there might be a huge ocean beneath its surface, beneath all the ice. And if this is said to be true, then the planet might have the ability to support life, and might even have life existing beings on the moon.

Europa

This moon is the second moon in our solar system that is being watched for the possibility of life forms already sprouting out there, recent studies discovered that the planet had plumes, this plumes happen because although Europa is a giant cue ball that is why it highly reflective, and not only does not reflect light, it is made up of rocky core, as well as sub-surface water. Europa is the second moon closest to the Sun and is also known as the second smallest planet. Also named after one of Zeus’s lovers.

Astrobiologist find this moon’s activities very fascinating and a mission is already underway that send an unmanned spacecraft in order to collect samples to be analysed for the water content found on the Europa

    WONDERFUL ARTICLE !!!

    Yes, the telescope was invented by an eyeglass maker in the Netherlands, named Hans Lippershey. He presented it to the Harbor Master so that they could see invading ships earlier and thereby have time to prepare for defense. It is legend that Galileo was the first person to point one up to the sky and keep records. These were the 4 moons of Jupiter that he could see with his little telescope, as they danced around the plant over days. (not sure I buy Galileo was the first to look up with “aid”. Having seen some Ancient Pre-History artifacts and even the Maya, some one had something to examine with and take measurements. Even the Sumerian clay writings seemingly have “at the time” unknowable knowledge of the planets like colors, some 7,000 years ago)

    Can’t wait for PART 2

      Thank you for your valuable feedback man! I will try to write on the new about chemistry but not part 2 on this article 😀 , hard to research on the source , and that is need more time to create article about science 🙂 Thank you for your reading my article and your feedback is appreciated! Greetings
