At 0:28 on February 3, China successfully launched the Beidou navigation test satellite into space with the long march 3A carrier rocket at the Xichang Satellite Launch Center. According to the person in charge of the relevant department, after the Beidou navigation test satellite was launched from the Xichang Satellite Launch Center on February 3, 2007, the satellite could not operate normally due to the failure of the solar panel

When a man-made earth satellite operates, its orbit radius is 1 / 9 of the orbit radius of the moon, then the operation period of the satellite is about?

From GMM / R ^ 2 = Mr ω ^ 2 = MR4 π ^ 2 / T ^ 2
T = radical 4 π ^ 2R ^ 3 / GM
T satellite / T month = radical r satellite ^ 3 / R month ^ 3 = 1 / 27
T satellite = t month / 27 ≈ 1 day = 24h

When a man-made earth satellite moves, its orbit radius is one third of that of the moon?
