Asteroid 9 Metis will reach opposition on Friday, August 28, 2026, making it easier to observe from Mexico. However, its brightness of magnitude 9.2-9.3 makes it invisible to the naked eye. A telescope and a star map will be required to locate it. The opposition will occur in the constellation Aquarius, around midnight local time. The asteroid will be approximately 1.399 astronomical units away, equivalent to 150 million kilometers. The bright Moon during the event will complicate observation. A partial lunar eclipse visible from Mexico between August 27-28 will also affect visibility. In Mexico City, the partial phase of the eclipse will begin at 20:33 on August 27 and end at 23:51. To maximize observation chances, it is recommended to find a location away from light pollution and use astronomy apps. The asteroid will appear as a faint luminous point among the stars, slowly moving relative to the stellar background.
