It took both astonishing intellect and resolute characters in the fields of optics and astronomy to unlock the many secrets of our Solar System. In a nutshell our solar system is situated between two of the Milky Way's spiral arms in an area,when compared to others,have relatively few number of stars in it. However the stars we happen to see when looking into the night sky are so far away from us that they are mere points when viewed through the largest telescope on earth,the LBT.
What though if our solar system was just a tiny bit closer to the centre of the Milky Way than it is at the moment then what? What then?Astronomists say that we would suffer harmful effects of being located amongst a dense concentration of stars. They also say that the Earth's orbit would be perturbed dramatically and that would be harming all life on earth. As it is,the solar system is just at the right position in the galaxy to avoid affecting our life.
Dangers to planet earth,had it not been so would be things such as,overheating when it passes through gas clouds,being expose to exploding stars and various kinds of deadly radiations.
The Sun...
This is an ideal star in our solar system. It is a steady burning,long living not too small,not too big and not too hot star that serve or needs. There are many more stars in our solar system and yet when compared to the SUN they don't provide the right kind of light,not the right amount of heat to sustain life on planet earth and are so much smaller when compared to the sun.
These smaller stars are also gravitationally bound to each other and revolve around one another. Our Sun is totally independent of that by contrast. If for some reason it wasn't the case and we had these other stars as our sun,then the likelihood of our solar system remaining stable when contending with gravitational forces would be virtually impossible.
The location of the Outer Planets is unique...
We have 4 giant outer planets in our solar system,Jupiter,Uranus,Neptune and Saturn. Yet these planets almost have circular orbits and still poses no gravitational threats to the smaller inner terrestrial planets whatsoever. We know that these outer planets play an important role in acting as protective absorbing and deflecting "tools" when dangerous objects passes through our solar system.
Scientists Peter D. Ward and Donald Brownlee wrote in their book Rare Earth—Why Complex Life Is Uncommon in the Universe:"Asteroids and comets hit us but not excessively so, thanks to the presence of giant gas planets such as Jupiter beyond us."
The Moon...
So much more than an object of attraction to poets and musicians,our Moon's gravitational pull causes the ebb and flow of tides. Its tidal movements that is fundamental to ocean currents which in turn are vital to our weather patterns. The gravitational force of the moon stabilizes the earth's axis in relation to the earth's plane of orbit around the sun.
Scientific magazine Nature wrote:"Without the moon, the inclination of earth’s axis would wobble over long periods of time from nearly 0 degrees to 85 degrees."
Astronomer Jacques Laskar says:"We owe our present climate stability to an exceptional event: the presence of the Moon. Imagine if earth’s axis had no tilt! We would miss the delightful change of seasons and suffer from a shortage of rain. The earth’s tilt also prevents temperatures from becoming too extreme for us to survive. To fulfil its stabilizing role, our moon is large and relatively larger than the moons of the giant planets."
How did all of this happen? By mere chance or by a Creator with a purpose? Are what's mentioned in this article merely a casual product of aimless chance or is there an intelligent and deliberate purpose behind it all? You be the judge of that.
Sir Isaac Newton(1642-1727)said:"The most beautiful system of the sun, planets, and comets, could only proceed from the counsel and dominion of an intelligent and powerful Being."
Albert Einstein (1879-1955)said:"I want to know how God created this world, I am not interested in this or that phenomenon, in the spectrum of this or that element. I want to know His thoughts, the rest are details. God does not play dice. Science without religion is lame, religion without science is blind."
Remember there are really only two alternatives when deciding which is which. Some would reserve their judgement on that
