What if Jupiter Doesn't Exists in Our Solar System?

Introduction and facts 

Sun is a storehouse of infinite energy, a blazing engine of fire and energy, which created life on a common planet like Earth and made it special from common. When it comes to the beginning of life on Earth, of course the Sun has played an important role both in this Solar System there is one other member which has always played the role of its bodyguard for the Earth. If the Sun originated the life on Earth, then it (the member) has contributed significant role to sustain that life. Yes, this is the fifth and largest planet of our Solar System, Jupiter. If seen rightly, then Jupiter is fully entitled to be the elder brother of the earth.

Today we will try to know that what would have happened if a planet like Jupiter would not have existed in our solar system?

First, let's talk about the birth of Jupiter. 

The Birth of The Sun And Earth's Bodyguard 

Around 4.6 billion years ago we can see a giant molecular cloud of dust and gas which has spread over many of light years. Yes, this is our initial solar system. With the gradual cooling of this dust and gas, gravity does its job. This dust and gas starts to be pushed towards the center. This causes the dust and gas to collapse together and become dense. It starts to become so dense and hot that it does not handle its own gravity and then collapse. After this phenomenon a new celestial object is formed called a protostar. Yes, it is our baby Sun. Now the Sun was born. Due to the gravitation the remaining gases and dust joined together to form a large particle like rocks and asteroids. The lighter elements like hydrogen and helium present in this dust and gas were pushed far enough away by the energetic solar winds of the newly formed sun. Where the effect of the solar winds becomes less to some extent, And these gases and dusts combined to form the first planet of the solar system, Jupiter. And the heavier elements remaining close to the sun were further transformed into smaller small terrestrial worlds. The early phase of the Solar System was a major upheaval (violent) when these inner planets of our solar system were being formed, compared to what we might see today as clean and stable, but is it really so? The answer is, May be yes or May not be. 

Yes, because most astronomers believe that this stable visible solar system and the reason for sustaining life on Earth is also the powerful gravity of the Jupiter, which has saved the Earth from the terrible danger of the solar system. Yes, here we are talking about comets and asteroids, especially of long period comets. Long period comets are those comets whose orbit is highly inclined and the orbital period is more than two hundred years. These types of comets are mostly pushed from the Kepler belt or Ort cloud towards the inner Solar System. Many scientists believe that most of the high speed comets coming from the outer Solar System, change their trajectory by the Jupiter's gravity and pushed them out of the solar system before they gets closer to the Earth, so that Earth survives from direct collision.

According to astronomers, the collision of the Earth with the long period comets occurs only once and a half times in millions or a billion years. If today, there is no Jupiter where it is then maybe life on earth never exists. Because then the collision with external comets would not be millions or billions of years, but only between a few thousand years, which is not enough time to develop a complex life form on the planet. 

The collisions

Many other strikes are likely going unseen. Indeed, a 2013 study led by Hueso estimated that Jupiter gets hit by objects between 16.5 feet and 65 feet (5 to 20 m) in diameter 12 to 60 times every year. Some of them is are below:

1). In the recent past years, astronomers have mapped some comets crashing on the Jupiter, of which the first comet 'comet shoemaker levy 9' was mapped to crash in the Jupiters atmosphere in 1994. The collision ended up being a multi-day extravaganza. From July 16 to 22, in 1994, 21 separate fragments of the comet smashed into Jupiters atmosphere, leaving blotches behindLater, when the results of this impact were seen, astronomers were quite surprised to see this result. The results were showing how terrible the collision must have been. Shoemaker-levy 9 was first spotted on March 1993 by three veteran comet discoverers: Eugene, Caroline shoemaker and David Levi.

2). The date was July 19 to 20, 2009. An amateur astronomer Anthony Wesley was photographing Jupiter from his backyard observatory in Murrumbateman, Australia, when something caught in his eyes. It was a comet. Don Yeomans, who is Nasa's retaired planetary scientist believes that it was a comet or asteroid longer than 100 meters. If it had hit the earth, it would have released as much as 2000 Megaton of energy which would have caused the destruction on a very large scale.

The 3 meter, infrared telescope facility at NASA, located in Muaana Kei, Hawai'i, revealed that the fresh cloud of debris that arose from this impact was like a mars planet. Later on July 23,2009 Hubble Space Telescope also captured this collision with the help of its wide field camera 3.

3). Another asteroid was filmed on 17 March 2016. A video was taken of Jupiter  on March 17 by an amateur astronomer, Gerrit Kernbauer, with his  20 centimeter telescope. During his filming, a light appeared on the right side of Jupiter as viewed from his lens. Another amateur astronomer, John McKeon, posted a video shot using an 11-inch telescope and an infrared filter of the same event, verifying the clip that Kernbauer. 

So these few collisions show that how important a role Jupiter plays to keep life on earth.

But does Jupiter play bodyguard every time for us?

The answer may be yes or no both, because the Asteroid Belt between Mars and Jupiter is always affected by the Jupiter's gravity. Due to which some asteroids pushed or move towards the Earth. Due to this, the possibility of asteroids hitting the earth always remains.

Conclusion

Has Jupiter always been playing the role of bodyguard or  not?

The answer may be yes or no. But we should really be thankful to Jupiter. Because it is the planet which gives the chance to form complex life form on                                                                       Earth.

You should tell us in the comment box what does Jupiter mean to you? Do you also think that Jupiter plays the role of being the bodyguard of the earth or do you consider it the opposite?
