MARS and COMET - NARROW ESCAPE from COLLISSION on 19th October 2014

"...the odds of an Earth impact in 2880 were estimated as 1 in 4,000 (0.025%) with a Palermo rating of −0.83.^[5][6]"

^{I'll take that bet.....}

^"...On March 5, 2001, 1950 DA made a close approach to Earth of 0.0520726 AU (7,789,950 km; 4,840,450 mi).^[8] "

1 lightyear = 5,878,625,373,200 miles

Thank you Mr.Solar Eagle,

for your comments. I will post some more details about this.

Don't worry dhayanandhan, Oct. 19th passed a few days ago; whew !

Dear Mr.Yahlasit,

Of course 19th October has gone. My question/doubt was/is when HUMAN EFFORT insight has not crossed 200 Light Years how it is possible to reach a distance and identify which is away by 874 years even though the present speed is about 60,000 K.M.

But at the present level of carbon-di-oxide one of the GREEN HOUSE GASES build up in the Atmospheric Air, if it reaches 800 PPM, the human race will extinguish from this MOTHER EARTH. Present level of CO2 has crossed 400 PPM, and it is estimated about another 130 Years the CO2 in the ATMOSPHERIC AIR will reach 800 PPM.

The trees and plants will happily prevent that from happening. Just so long as we allow them to grow.

And if the sun keeps on shining, they will produce sugar for them and for us as well.

Dear Mr.Brave Sir Robin,

The Deforestation, is in the EVER INCREASING RATE. It has been estimated that for atmosphere Equilibrium, the forest coverage should be 1/6 of LAND SURFACE where as it is presently (as estimated by Mauna Lab during Jan 14) it is 1/11 of Land Surface, and at the end of this century it will be 1/32.

Then where is the question of trees and plants will protect us by converting CO2 to O2.

MAN IS THE FIRST and WORST ENEMY TO THE NATURE and MOTHER EARTH.

Yeah, yeah, I know we'll all die. And then the earth will be so much better off without us. So what's the problem?

Actually, the farthest observable objects in this universe are at 13 BILLION light-years.

You can see stars with your naked eye that are (or were once) located at far greater distances in any normal night with no clouds.

If your statement were correct, we would see many stars disappear constantly and many others suddenly appear, just think about it.

Aren't there building codes governing narrow escapes? As professionals with capacity for abstract thought, we should be concentrating on this.
