You are here living on a ball of cooling rock as far as we know within an ordinary Solar System.
Consisting of 8 or so planets depending on categorizations could be 9 or even more; planet means wanderer so really there are only Mercury,Venus, Earth, Mars, Jupiter, Saturn that can be see with the naked eye is 6.
Between Mars & Jupiter there are 1,000's of asteroids a few nearly as big as the moon and if Pluto is a planet so are they: Ceres & Vesta (they were previously said to be Planets)
The 3 inner planets including our Earth is small in comparison to the larger outer Gas giants.
(approx. 1,321 Earth's could fit in Jupiter and 1.3 Million inside the Sun).
(approx. 1,321 Earth's could fit in Jupiter and 1.3 Million inside the Sun).
We have sent 99 missions to space of which 9 are still travelling out such as Voyager 1 & 2 and New Horizons; still sending back data.
It took nature 4.5 billion years to create Humans to do this.
Apparently life started on 300 million year after the Earth first cooled!
We may last 100's, or 1,000s of more years but as we are gobbling up resources vital to our current way of life some estimate we will go backwards, either that or some disaster will curtail us.

Estimates of stars like our Sun are billions all revolving around a central core of more dense ones and possible a black hole, the whole diameter of the Milky Way galaxy we reside within maybe 100 to 120 thousand light years across or even nearly twice that.
We can shorted this representation to 100–180 kly (31–55 kpc) & ≈2 kly (0.6 kpc) thick.
A light year is approx 6 trillion miles / 9½ trillion Km.
A parsec is ~ 3.26 ly.

At this level, it is estimated that the there are 1080 (between 1078 to 1082) atoms in the known, observable universe. In layman’s terms, that works out to between ten quadrillion vigintillion and one-hundred thousand quadrillion vigintillion atoms. How Many Atoms Are There in the Universe?
Earth has 1.33*1050 Questions and Answers - How many atoms are there in the world?
These are huge number and your body has A 70 kg body would have approximately 7*1027 atoms. Questions and Answers - How many atoms are in the human body?
