While many 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. They are so short thinkers & egoistic that they forget that a day will come when they are grand parents or parents.
As of now there are humans on this planet and if we see them one day, hope they dont have such human attitude. See more information at the end of the earth page.
Mercury

Terrestrial Planet

The smallest planet in our solar system and nearest to the Sun, Mercury is only slightly larger than Earth's Moon. Mercury is the fastest planet, zipping around the Sun every 88 Earth days.

From the surface of Mercury, the Sun would appear more than three times as large as it does when viewed from Earth, and the sunlight would be as much as seven times brighter. Despite its proximity to the Sun, Mercury is not the hottest planet in our solar system – that title belongs to nearby Venus, thanks to its dense atmosphere.
