Monitoring the passage of the asteroid "Semiramis" in the sky of Umm al-Qaiwain

A team from the International Astronomy Center today managed to observe and photograph a rare astronomical phenomenon, represented by the passage of the asteroid "Semiramis" in front of a star of the group "Parshaus".

The center said that the monitoring process was difficult because of the low light of the star and the asteroid, the star shone from the ninth degree and the asteroid from of the eleventh degree. These values ​​make it possible to see the phenomenon only with the help of precise devices and in a relatively dark place. The phenomenon can only be observed from a certain area, which is a narrow band not exceeding ten kilometers, that crossed the United Arab Emirates from the west coast north of Umm al-Qaiwain and heading towards the East, it ended at the east coast north of the city of Dibba Fujairah. After studying the trajectory, the team discovered that the most appropriate place to monitor the phenomenon was in the Umm Al Quwain emirate desert, four kilometers south of Al-Marjan Island, towards the desert, because of its exact location on the containment path. Monitoring.

According to the center, the diameter of the asteroid of Semiramis is 57 km.

Astronomical calculations have shown that the asteroid will pass before the star On Tuesday morning, October 30, the alarm will begin at 2:40:55 and the delay will only last 11 seconds. During this period, the asteroid does not disappear because of the small size of the asteroid. . The team arrived at the observation site at sunset and preparations began to monitor the phenomenon at 10 pm. Once the telescope was pointed at the star, the team was able to see the star . The asteroid was very slightly visible to the right of the star and was getting closer. The star until the delay occurred on the same predetermined date, and after several minutes of the end of the block, the team was able to see the asteroid to the left of the star.

Astronomical observations are astronomical phenomena that provide scientists with valuable information through which many discoveries have been made, including the discovery of the Uranus and Neptune rings, the determination of the diameter of certain stars, the shape of the edges of the moon and the shape and size of some asteroids, as well as the identification and revision of the orbits of the planets and the solar system.
