100,000 times around Earth's orbit

As of 7:42 pm on 10-8 hours EDT (ie 18: 42 minutes on the same day in Hanoi), the Hubble telescope has traveled around 100,000 times.

Thus, since the Discovery spacecraft launched into orbit at 611 km in 1990, so far after 6,684 days, Hubble has traveled more than 4.37 billion km with an average speed of over 28,100 km / h .

According to the calculation of the Space Telescope Science Institute (STSI) of the United States, Hubble management unit, this distance is equivalent to 5,700 rings flying around the Moon.

According to STSI, Hubble telescope can aim at a angle of more than 7/1000 arcseconds (like seeing a hair at a distance of 1.6 km).

Typical Hubble findings include: Solar extrasolar planets, the formation and destruction of stars, determining the age of the universe, the boundaries of space .
