The stars can be used to keep time. a) If we see the full cycle of constellations in a year by what amount of time does a particular star rise or set earlier each night? b) If Vega sets at midnight tonight at what time will it set 1 month from now? c) If Altair rises at 2 a.m. tonight how long before it will rise at midnight? I don’t understand how from the fact that the stars rise 0.98 degrees earlier each night we can estimate the time? The image provide the expert answer but I don’t understand it

09:22 recognized shape or figure. These star patterns are used to traverse the night sky and convey myths or stories about celestial objects. They have been discovered and named by numerous cultures throughout history. Step2 b) a. The Earth's orbit around the Sun is what causes the constellations to rotate through one year in full. In a year, the Earth revolves around the Sun approximately 360 times. As a result, divided by 365 days, the stars rise and set on average about 360 degrees per night, or 0.986 degrees sooner each night. Step3 c) b. If Vega rises at midnight tonight, it will rise at roughly 10 p.m. one month from now. This is so because Vega sets around 0.986 degrees earlier each night, and there are typically 30 days in a month. c. Altair will rise at midnight nearly 10 months from now if it rises at 2 a.m. tonight. This is due to the fact that there are around 365 days in a year on average, and Altair rises 0.986 degrees earlier each night, which results in a shift of 10 months over the course of a year. @ √x Do 8
