Dark Object Investigated While Making One of the Closest Ever Comet Flybys of Earth

These radar images of comet P/2016 BA14 were taken on March 23, 2016, by scientists using an antenna of NASA's Deep Space Network at Goldstone, California. At the time, the comet was about 2.2 million miles (3.6 million kilometers) from Earth. Credits: NASA/JPL-Caltech/GSSR

Astronomers at the Planetary Science Institute made observations of Comet Pan-STARRS (P/2016 BA14) using the NASA Infrared Telescope Facility (IRTF) on Mauna Kea, Hawai’i that show that it reflects less than 3 percent of the sunlight that falls on its surface. For comparison, fresh asphalt reflects about 4 percent of the light that falls on it.

Comet Pan-STARRS made a close flyby of the Earth at a distance of 3.6 million kilometers (2.2 million miles) on March 22. This is one of the closest flybys of a comet in recorded history and the last one to come closer was Lexell’s comet that flew by the Earth at a distance of 2.2 million kilometers (1.4 million miles) on July 1, 1770. 

“We measured the spectral and thermal properties of the comet using the NASA IRTF and found that the comet reflects between 2-3 percent of the sunlight that falls on it,” said Vishnu Reddy, research scientist at the Planetary Science Institute in Tucson, Arizona. “This is typical for comets,” Reddy added. Based on its reflective properties, Reddy estimates the size of the comet to be between 600 meters and 1.2 kilometers (0.4 miles and 0.75 miles) in diameter. 

Comet Pan-STARRS was originally discovered as an asteroid and later found to have cometary properties when astronomers realized its orbit is similar to another short period comet 252P/LINEAR, which also made a close flyby of the Earth at 5.3 million kilometers (3.3 million miles) on March 21. 

"It is an extremely rare opportunity to be able to study a pair of comets with historically close flybys. Measuring the physical properties of both comets will help us understand the evolution of comets in general," said Jian-Yang Li, Senior Scientist at PSI. Li was observing 252P/LINEAR with the Hubble Space Telescope during its close encounter.

This research was funded by NASA Near-Earth Object Observations program. The Infrared Telescope Facility is operated by the University of Hawaii under contract NNH14CK55B with the National Aeronautics and Space Administration.

  1. There are only two views of History: one, that everything happens by accident; and two, everything occurs by design. The former view is held by the ignorant, the fool and the liar, the second is held by the wise. History is made by design and not a product of happenstance. Two public figures separated by time understood this. Franklin D. Roosevelt (1882-1945) the 32nd President of the United States said: “Nothing in politics ever happens by accident. If it happens, you can bet it was planned that way.” Benjamin Disraeli (1804-1881) Prime Minister of Britain wrote: “The world is governed by people far different from those imagined by the public.” These two simple statements illustrate the basic premise which underlies the substantive and proper study of History: that every major event in politics, economics, finance and international relations are the products of calculated power moves by secret cabals bent upon controlling the world absolutely and forever. In short: that History is made by hidden powers working according to preordained plans. Consequently, those who understand this, that History is made by largely unseen forces, also understand and can perceive this ongoing titanic power struggle within the historical process. A fateful struggle that constantly shapes the present in preparation for the planned future, yet, which is neither recognized or understood by most people. That is why those who do not recognize this reality find current events baffling and modern diplomacy illogical no matter how diligently they follow the “news” pumped out by the controlled media
    Surface politics of “two party” opposition and rivalry – of high political theatre- are simply smoke and mirrors masking the true stratagems orchestrated by these hidden puppet-masters that have control of these supposedly rival parties. The “Two Party” system in the US and Britain is a myth. Both sides, the “Right” and the “Left,” “Capital” and “Labour,” “Conservative” and “Labour,” “Republican” and “Democrat,” are in the thrall of this cabal of power and enact legislation that ultimately draws the world towards the New World Order. Parliamentary goings-on are now simply a Punch and Judy show for the ignorant masses. Consequently, diversions, spurious political party lines and false concerns are stirred-up to confound proper understanding of the reality … of the truly dire situation that faces us all. Acts of one government and policies of another conceal the stealth of these hidden masters. Moreover, as low-level debate on very mundane matters occupies people, diverting attention and confounding proper understanding, this evil cabal digs ever deeper into the Soul of the World.
    However, Christ informed us that the only reason for habitual secrecy by organized men is to hide their evil (John 3:19-20; 18-20). Thus, the habitual secrecy of the Empire of Secret Societies is designed to not simply conceal occult ceremonial and ritual tomfooleries but a great and terrible secret: that they are the main vehicle of Evil on Earth and seek to eradicate God’s presence on Earth. And, those with eyes to see and hears to hear can perceive this wholesale corruption of society and see many men in high places living under the Sword of Damocles … For, in the final day, these men and women who have willingly and unwittingly advanced this Evil Agenda will have to face Christ and justify their actions: during the day when all men will stand before Christ and will be judged for their deeds For, Christ, sitting on the Great White Throne of Judgment, will judge all men according to their works, for, He is verily the Lord God (Rev. 20:11-15). The best way to fight the mostly unseen forces and the habitual secrecy by organized men is by repentance and prayer (If My people who are called by My name will humble themselves, and pray and seek My face, and turn from their wicked ways, then I will hear from heaven, and will forgive their sin and heal their land (2 Chronicles 7:
