When you have a big brother or an elder sister then you know that you will be a little safe! You will be protected or at least guided!
You would know what to do and more importantly what not to do!
The expectations would be lesser and the stress too!
Do you know that even the Mighty Earth has a big brother or sister who protects it and has been doing it for millions of years!?
This mega or giant planet is Jupiter which revolves the Sun once in twelve years which is maybe why the Maha Khumbh Mela is celebrated once in twelve years!
In Carl Sagan’s Cosmos it has been said that Jupiter is a failed star because it is made of the same elements (hydrogen and helium) as is the Sun, but it is not massive enough to have the internal pressure and temperature necessary to cause hydrogen to fuse to helium, the energy source that powers the sun and most other stars.
However, Jupiter has only about 0.1 percent the mass of the sun, and as it is definitely not a star, we can’t really call the solar system a double star.
If Jupiter had tried little more then we would be a two star system! And the day would be 24 hours! No nights at all! But then I love the night since it makes me appreciate the day more! And of course normal people sleep in the night! So what if Jupiter is not a star! It is a star planet!
And more importantly it is the big brother or sister protector of the Earth!
Some astronomers believe that one reason Earth is habitable is that the gravity of Jupiter does help protect us from some comets. Long-period comets, in particular, enter the solar system from its outer reaches.
Jupiter’s gravity is thought to sling most of these fast-moving ice balls out of the solar system before they can get close to Earth.
So long-period comets are thought to strike Earth only on very long timescales of millions or tens of millions of years.
Without Jupiter nearby, long-period comets would collide with our planet much more frequently. But Jupiter creates both good and bad conditions for earthly life just like any elder brother or sister gives you challenges in life to make you stronger!
Consider that its powerful gravity prevented space rocks orbiting near it from coalescing into a planet, and that’s why our solar system today has an asteroid belt, consisting of hundreds of thousands of small flying chunks of debris! If you are planning to go beyond the realms of the solar system then apart from the basic issues of space flight; you must cross this obstacle course to succeed!
You of course can succeed only by training and asking questions! Reminding me of the one who always has a question ready! Arnab Ranjan Goswami!
Now if the answer to the question, ‘Are you sleepy?’ in affirmative then please sleep!
Shubh ratri!
