What fractional decrease in flux, δF/F, would be caused by an Earth-like planet transiting a Sun-like star? If a transit of the Earth across the Sun were viewed by a very distant observer in the Earth’s orbital plane, how long would the transit last?[Hint:You will need the orbital velocity of the Earth,vorb= 30km s−1.]
