The site architect requests for some interesting Astro Spinnets for their jogging placards; something astrological - ie comet/planet related,
when is the next comets coming, Near Earth Objects,etc.
Examples :-
Near Earth Object (NEO)
A Near-Earth Object (NEO) is an asteroid or comet whose orbit brings it close to the Earth; this includes an object that will come close to the Earth at some point in its future orbital evolution. NEOs generally result from objects that have experienced gravitational perturbations from nearby planets, moving them into orbits that allow them to come near to the Earth.
1st Historical View of Impacting Comet on Jupiter
In 1994, over the course of a week in July, fragments of comet P/Shoemaker-Levy 9 collided spectacularly with Jupiter. Comet fragments, each up to two kilometres in size, collided with the atmosphere of Jupiter, sending out plumes many thousands of kilometres high. This was the first event of its kind - a major collision between two bodies of the solar system - to be directly observed, and was instrumental in making scientists and the general public alike think of the possibilities of something similar happening to Earth.
Where is Halley Comet Now ?
This famous comet was the first to be recognised as a periodic comet. Astronomer Edmond Halley deduced that the bright comets seen in the 1531, 1607 and 1682 were all the same comet and predicted to return in 1758. And true enough it was there!. Comet Halley passes close to Earth approximately every 76 years and brightness vary with each passing. Probably the best appearance was in 1837, when Halley’s comet reached a magnitude of –3(almost as bright as Venus), and its tail covered more than 60 degrees in the night sky.
Halley’s last appearance in 1986 was relatively disappointing and could be seen in Singapore then as a dim hazy patch of light at it best in April that year. As of 2005 Halley comet is about 30 au (30 times Sun-Earth distance) from Earth in the constellation ‘Hydra’. It will return to Earth around year 2062.
The names of the seven days of the week were based on the names of the celestial objects originally considered to be planets: the Sun, the Moon, Mars, Mercury, Jupiter, Venus, and Saturn.
The universe is so vast in relation to the matter it contains that it can be compared with a building twenty miles long, twenty miles wide, and twenty miles high that contains only a single grain of sand.
I will need more of the above; preferably more on NEO, potential effect on Earth existence cause by external bodies, etc...
Appreciate any inputs and those selected for actual placement will be guaranteed a visit to the Observatory & maybe even a 1 night stay
Thank you !

- shock tactics, maybe that's will lead to more residents wanting to verify the 'Truth' and visit the Obs more often.
