The increasing tracking of the sky has increasingly allowed the observation of meteors in Brazil. This was the case of the recording of a fireball that crossed the sky in several cities in the interior of São Paulo and other regions of Brazil last night.
The phenomenon occurred with the entry into the atmosphere of a rock from space that entered the Earth’s atmosphere at 9:35 pm on Tuesday (15).
According to the Brazilian meteorological monitoring network, Bramon, the space rock reached the earth’s atmosphere at an angle of 18.6 ° with the ground, at a speed of 13.52 km / s (34.4 thousand km / h).
The fireball was observed in the states of Minas Gerais, São Paulo and Mato Grosso do Sul. The space rock crossed the sky in an easterly direction for 11.6 seconds, until it disappeared at an altitude of approximately 25.3 km southwest of the municipality of São Paulo. Votuporanga.
At its peak, the meteor still reached -9.5 on the magnitude scale, used in astronomy to measure the brightness of celestial objects. This means that the fireball was about 100 times brighter than the planet Venus. Meteors brighter than Venus are also called “fireballs.”
