Title: Alert: For The Times, Book of Secrets
Comet Ison made the closest approach to the Sun on Nov. 28, 2013. It came from the Oort cloud, over 4.5 trillion miles away. This was U.S. Thanksgiving Day. That day marked the crescendo when it passed just 1.1 million kilometers from the surface of the Sun. A remnant made it around, but most of it disintegrated. The comet was discovered by Artyom Novichonok and Vitali Nevski on September 21, 2012 as part of the ongoing International Scientific Optical Network (ISON) survey. It never even got close to Earth.
We have new figures for NEOs, Near-Earth Objects. As of March 2023, NASA had identified around 31,000 NEOs. Around 2,300 are considered hazardous. A pesky small asteroid came close to Earth on Jan. 26, 2023, when it flew above the southern tip of So. America at 2,200 miles (3,600 Km.) Diam. only 3-8 meters (little truck). The Asteroid 2023 TK15 following site is interesting, as is this one from Physist Professor Michio Kaku, and the following:
The comet, scientists tells us, was not visible as it approached the Sun, via NASA Solar Dynamic Obs (SOHO) or from any earth observatories, but, was visible in STEREO and SOHO images. No substantial fragments of ISON were visible as the remnants headed back towards our planet and out to space. If you saw any of these memorable tidbits or bolides or meteorites, we would ask you to report it to the American Meteor Society, or go to AMS Report .
