Arccording to Nasa, the Kepler telescope will be working for 3.5 years in orbit and during that time it will observe about 100000 stars looking for exoplanets. Howcome it can finish for that workload?
Thanks for the reply.If you could only look at one star at a time (not true), this works out to 20 minutes per star. If you can look at 100 stars at once, that's one day per star field. 1000 stars? A week. This doesn't sound unreasonable.
By transit do you mean revolution? Transits only last hours, while revolutions are on the order of months and years.Thanks for the reply.
I am still confused that when focussing at one star, the Kepler Telescope should maitain the position for at least one period of a transit (if there is one), and the period is offen of months if not years.
One more thing, if K. telescope looks at 100 stars at once, is it possible to detect any wink in one individual star?
Sounds to me like it's going to stare at the same patch of sky for the entire mission. Thus, any planets with an orbital period of up to 3 years have a decent chance of being detected.I don't think Kepler is designed to focus on individual stars, but rather has at larger field viewing area and measures the brightness of the stars in that field.
Simple: It looks at 100,000 stars all at once and looks at the same 100,000 stars during the entire 3 1/2 year mission. Kepler is looking for transits, so catching one requires continual monitoring.If you could only look at one star at a time (not true), this works out to 20 minutes per star.
