Asteroid: 7335 (1989 JA)

~~ a short essay ~~

The world has been watching to see if an Apollo-class asteroid, provisionally referenced as 7335 (1989 JA), would come closer to Earth than predicted by NASA. “Four times the size of the Empire State Building and travelling 20 times faster than a speeding bullet” (Specktor, 24 May 2022), some scientists have said the asteroid’s path was too close for comfort. “If the projected trajectory across our orbit had deviated, it could have hit Earth” (Specktor, 24 May 2022). However, Specktor cautioned, “the likelihood of that happening was pretty small considering the fact its path circumvented Earth by a mere 2.5 million miles.” He added, “the Earth will not encounter the orbit of 7335 (1989 JA) again until its next flyby on 23 Jun 2055.”

The rocky mass, “was first detected 1989 by astronomer Eleanor Helin at the U.S. Palomar Observatory in California,” (Eds. Wikipedia, 26 May 2022). The editors at Wikipedia quoted Mainzer, A; Gray, T.; et al. in saying, “a survey by NEOWISE (a mission of NASA’s Wide-field Infrared Survey Explorer)” the asteroid has an albedo of 0.31–0.32, which is more than twice the albedo of the Moon’s reflector score of around 0.14–and half again the typical albedo for stony asteroids.” (Mainzer, A.; Gray, T.; et al, August 2011). According to Wikipedia’s page, Albedo, “unusually high radar albedo is indicative of high metal content in asteroids (27 May 2022).

I believe family is a gift from God and should be treated as such. I love writing with a broad array of intent and purpose. I have written poetry virtually all my life, and much nonfiction in academia. My expanded efforts in all areas have finally taken off in retirement. I have much to accomplish now that I have the time. Other hobbies are painting, researching ancestry and myriad topics for my writing, knitting, crocheting, cooking -- always trying new recipes and always cooking for my health. I have many other hobbies, but these seem to dominate most of my time. Oh, did I mention I am the mother of three grown children and grandmother of seven. I have been blessed immensely and am the happier for it.https://twitter.com/tkbrownwriter/photo
