In the mid-nineties, the planetary world was very small and consisted of only nine planets in the solar system. Pluto’s planetary status had not yet been challenged. Despite this small world, these planets had a diverse atmosphere. We couldn’t even imagine it. Cameras mounted on spacecraft fleets were exploring the solar system, exposing alien worlds to us, teaching us astronomy.
Importance Of The Planets:
Let alone life, and we were not even aware of the importance of the planets on a cosmic scale at that time. For the first time today, scientists are looking at planets and life as an integral part of the universe and its history. We are doing what we can in this quest.
Types of Planets:
The planets in our solar system form two types. The gas giant and the terrestrial planet, Jupiter is ruling over all the planets due to its name and anatomy. It is still a mystery, as it took scientists about two and a half thousand years to confirm its mass and volume. Four hundred years ago in Padua, Galileo Galilei first looked at Jupiter using his extraordinary visual instrument, the telescope. Galileo saw a planet, orbiting four moons, instead of a star. He named them Medicean stars. He named it after his Florentine mentor, Medici. Until then, the difference between stars and planets was not clear.
How Did The Ancients Understand This?
We now know them as the Galilean moons of Jupiter. The orbits of these moons have helped us to measure the gravitational pull of the planets and their mass. (Here I have used the word mass. The mass of anybody is measured by the material in it (atoms or matter). Mass and gravity are interconnected: The force of gravity depends on mass. A thicker body produces a stronger force (or tension). This is not true, and its use can lead to complications, so I will only use words of quantity or thickness. This measure was the victory of Isaac Newton’s law of gravity, which She was a guide for the generation of scientists who followed Galileo, who helped the young Immanuel Kant solve the process of forming the planets. Jupiter is actually a giant planet, compared to Saturn, the only distant circular planet.
Jupiter and Saturn:
Jupiter is a gas giant. We know this by its average density. Its diameter is ten times larger than Earth’s, making Jupiter a thousand times larger. Given that Jupiter’s mass is only three hundred times that of Earth, it has been estimated that it must be made of matter that is lighter than our rocky Earth. In fact, Jupiter and Saturn are mostly made up of hydrogen and helium, which are the most abundant elements in the universe, and they are also the lightest elements. They are largely made of matter like the sun and stars.
Some Planets Resemble the Sun:
Our system’s largest planets resemble the sun in another way. They have no concrete surface or geography. As we descend from the atmosphere we see with our own eyes, there are only clouds and clouds that go deeper and thicker and warmer. Most of the hydrogen and helium inside Jupiter withstand this air pressure a million times more than the Earth. One of the reasons for such tremendous pressure is that the larger the planet, the greater it’s pulling power. I would weigh 2.4 times more on Jupiter. If we risk going deeper into the planet the way we dive into the ocean, the pressure will increase.
