Nasa is tracking a newly discovered asteroid that has a 'small' chance of hitting Earth on Valentine's Day 2046

I will be 50

The next sentence says they predict a small chance of impact.

That's the European Space Agency, not NASA.....
​

These calculations are nonsense. NASA just has to look like its doing something in order to keep the ponzi scheme going

Last I checked, NASA ain't in Europe.

So, again, how do you know NASA's calculations are wrong? What calculations have YOU performed to show their error?

No, you don't need to know the 'manner' they came up with the calculations. You need to know the calculations since they haven't been wrong for several hundred years.....

.... and are responsible for discovering Uranus, Neptune, Pluto, and several other celestial bodies.



And, no, they don't use infrared thermal imaging. They use spectroscopy.

Like I said, your objections just make you look stupid.​

 

[MrLogic]

Will we even make it to 2046

something gonna come to a head for usa

and it will not be good.

 

[Elim Garak]

A non-issue for coliBrehs. Most of thecoli will be too senile to care by then. Isn't our average age on here 40?

How many senile 60 year olds you know?

Well it says NASA at another point in the article

"A newly discovered asteroid may make a perilously close approach to Earth about 20 years from now, with a roughly 1-in-600 chance that the space rock will collide directly with our planet, officials with NASA's Planetary Defense Coordination Office tweeted.
While that's a higher-than-average risk level for near-Earth asteroids, it's still a "very small chance" of impact, NASA wrote —"


Also tomatoe tomota

"NASA and ESA (European Space Agency) have worked together on multiple missions to advance our understanding of the Sun and its effect on Earth."


So they were just cosigning NASA basically.And i wasnt sure how they dicovered Uranus and Neptune,but google says telescopes. No debate with that technique.

 

[GreenGhxst]

That's a good time for it to hit, by that time I'd be early 50s

It's a good chance I'd be sick of these nikkas, cacs, brehitos and every other living human being on this mf

Just fully into my old man bitter stage, good time to lights out earth

Neptune was discovered by use of celestial mechanics.....

Neptune

Astronomy articles from In-The-Sky.org: Neptune

in-the-sky.org

The discovery of Neptune is often seen as the greatest achievement in the history of celestial mechanics, because the planet's presence was predicted before it was seen.

A year before its discovery, two mathematicians, Urbain Le Verrier and John Couch Adams, had studied the orbit of Uranus and observed that it showed significant deviations from the elliptical path which Newton's laws dictated it ought to follow. One way to explain these was the presence of another massive planet nearby, exerting a gravitational distortion its orbit.

So good were the predictions made by Le Verrier and Couch Adams, that when Galle found Neptune, it lay a mere one degree from the position predicted, though this was largely due to good luck: there were in fact substantial inaccuracies in Le Verrier's workings.

The article says it was largely due to luck,not me

"around the same time, Le Verrier's also noted that Mercury's orbit showed similar anomalies, and he used the same logic once again, proposing another hypothetical planet, dubbed Vulcan, which orbited even closer to the Sun than Mercury.

This time Le Verrier was to be disappointed, and Vulcan was never found. The puzzling anomalies in Mercury's orbit remained unexplained until Albert Einstein showed that Mercury's orbit lies sufficiently close to the Sun for relativistic effects to become apparent."


Also you said they dont use thermal infared for asteroids. But NASA says they do

No, it doesn't. Mercury =\ Neptune.
​

They don't use it to determine what celestial bodies are MADE of, their surface, or their shape, but to detect them in the first place.
​

They use infared thermal imaging like The Predator. But they have to use guesswork and make assumptions about the makeup of the asteroid,its surface and the shape.

And, no, light is not a 'force'. Light is energy. It can exert a force on things (like solar sails...see LIGO). Force is a measure of how strongly objects interact. Light's interaction with celestial bodies the size of asteroids and larger isn't a factor since it is composed of photons which are massless.​

Your article says he largely found Neptune due to luck. And his same calculations and assumptions made him think there was a planet near Mercury,but he didnt find anything. So he got lucky the first time according to your article,and didnt find shyt the second time


Oh you havent heard,NASA has new billion dollar technology now

"But to learn more about these elusive and important celestial objects requires a different type of instrument. An infrared sensor can, in the right circumstances, not only provide data on an asteroid’s orbit and data that can be used to more accurately measure its size, but also chemical makeup and sometimes even its surface characteristics.

"NASA’s Near-Earth Object Wide-field Infrared Survey Explorer, or NEOWISE, spacecraft, in orbit around Earth, uses asteroid-hunting thermal sensors that allow an infrared view of asteroids without the obscuring effects of Earth’s atmosphere. In a paper published recently in the journal Icarus, researchers led by Josef Hanuš, a scientist at the Astronomical Institute of Charles University, Prague, have made an in-depth analysis of more than 100 asteroids that have come under the temperature-sensing gaze of NEOWISE. "


Not sure what your definition of large is. But this article says light would have a "small but significant force" on asteroids smaller than 30-40 km. A 30 kilometer asteroid would cause major damage if it hit earth.

"The Yarkovsky effect describes a small but significant force that affects the orbital motion of meteoroids and asteroids smaller than 30-40 kilometers in diameter. It is caused by sunlight; when these bodies heat up in the Sun, they eventually re-radiate the energy away as heat, which in turn creates a tiny thrust. This recoil acceleration is much weaker than solar and planetary gravitational forces, but it can produce substantial orbital changes over timescales ranging from millions to billions of years. The same physical phenomenon also creates a thermal torque that, complemented by a torque produced by scattered sunlight, can modify the rotation rates and obliquities of small bodies as well. This rotational variant has been coined the Yarkovsky-O'Keefe-Radzievskii-Paddack (YORP) effect. During the past decade or so, the Yarkovsky and YORP effects have been used to explore and potentially resolve a number of unsolved mysteries in planetary science dealing with small bodies."


So I rest my case,light is basically a force. And you would have to take it into account which is impossible based on my calculations#SimpleMathmatics

Your article says he largely found Neptune due to luck.

It was 1 degree away from where he predicted it to be using celestial mechanics.

1 degree =\ Luck, but math, meaning he got the right answer despite his calculations being off.

You didn't read that correctly. The 'force' is thrust ....."when these bodies heat up in the Sun, they eventually re-radiate the energy away as heat, which in turn creates a tiny thrust. "

Light doesn't move the object (strength of interaction) so your case is dismissed.

It is not a force.
