This is like the beginning of some sci fi movie. A huge red obelisk-shaped "rock" enters our solar system--strange but unassuming. Soon it enters our orbit and alas, a swarm of aliens emerge from it and invade our planet in a clever Trojan horse ploy.
"Astronomers are now certain that the mysterious object detected hurtling past our sun last month is indeed from another solar system. They have named it 1I/2017 U1(’Oumuamua) and believe it could be one of 10,000 others lurking undetected in our cosmic neighbourhood.
The certainty of its interstellar origin comes from an analysis that shows its orbit is almost impossible to achieve from within our solar system.
Its name comes from a Hawaiian term for messenger or scout. Indeed, it is the first space rock to have been identified as forming around another star. Since asteroids coalesce during the process of planet formation, this object can tell us something about the formation of planets around its unknown parent star.
The latest analyses with ground-based telescopes show that ’Oumuamua is quite similar to some comets and asteroids in our own solar system. This is important because it suggests that planetary compositions like ours could be typical across the galaxy.
It is thought to be an extremely dark object, absorbing 96% of the light that falls on its surface, and it is red. This colour is the hallmark of organic (carbon-based) molecules. Organic molecules are the building blocks of the biological molecules that allow life to function...."

26.32 Kilometers every second =
60 seconds times kilometers = minutes = 1579.2 Kilometers per minute
times 60 minutes to get Kilometers per hour
1579.2 times 60 minutes =
94,752 Kmph
A first observation, but certainly not the first time this has happened. It has probably happened time and again over the entire history of the Earth. Just one more way we could all be wiped out to add to the list. Don't worry, be happy.
