NASA discovers ‘asteroid’ near Earth is actually a hidden comet after decades of mystery
A NASA study has reclassified a celestial body previously thought to be an asteroid. This object, known as 1998 SH2, is now identified as a comet. Researchers used advanced observatories to detect its faint tail and activity. This discovery aids in identifying potential space dangers and misclassified objects. Future missions will help track such celestial bodies more accurately.
NASA Study Finds Near-Earth Asteroid Is Actually Comet
The object looks like an asteroid but moves like a comet, so astronomers used some of the most powerful observatories on the planet to confirm its identity. New research […] The post NASA Study Finds Near-Earth Asteroid Is Actually Comet appeared first on Astrobiology.
Since its discovery nearly 30 years ago, comet SH2 had shown no clear signs of being a comet in 1998. However, new analyses, combined with historical international observations, reveal a different story. Dark comets are divided into two distinct groups. Outer dark comets are larger and have more eccentric orbits, while smaller inner dark comets have more circular orbits. Near-Earth object 1998 SH2 made its closest approach to our planet at a saf…
Missing ‘Asteroid’ Tracked Since 1998 Turns Out to Be a Rare Dark Comet, Scientists Say
An object that astronomers believed was an asteroid for nearly three decades has been reclassified as a rare “dark comet” after unexpectedly deviating from its predicted orbit. Known as 1998 SH2, the object puzzled researchers when it failed to appear where calculations predicted it would in 2025. Follow-up observations and a year of analysis revealed that the object was exhibiting subtle comet-like behavior, despite lacking the bright tail and …
