Planet Neptune

Dark, cold and whipped by supersonic winds, ice giant Neptune is the eighth and most distant planet in our solar system.

More than 30 times as far from the Sun as Earth, Neptune is the only planet in our solar system not visible to the naked eye and the first predicted by mathematics before its discovery. In 2011 Neptune completed its first 165-year orbit since its discovery in 1846

While many people on earth do not care for their parents,
some on earth purposely do not see their father, grand father, father in law who has left life but is about to leave this earth.

Science increases age.
These born humans are so myopic thinkers & are so egoistic that they forget that
a day will come when they are grand parents or parents.
What is their children or grand children ask them : Did you see your father or grandfather or father on law when he was about to leave earth ?
Only they can tell you.
While we keep privacy, it will be known worldwide if they kill related persons or do accdident in such a way that they will think nobody will know the truth. But we believe in police and the mental as well as physical science they use to know the truth.
And they even can play smart life game by asking
their neighbours or relatives or friends in legal or medical system to do it, thinking they are free. But world will know the truth one day (when they are alive or dead. At least their grandson or graddaugher will know it)

As of now, we think there are humans on this planet and if we see them on another planet one day, we dont want this egoistic attitude transferred to them, not even robots.
