how does the size of planet eclipsing a star effect the brightness of the star?
thanks.
thanks.
Roughly proportional to the visible fraction of the surface area, yes. There are effects like limb darkening that complicate the picture a bit, but for the most part, eclipses can be modeled as simply as this.skiboka33 said:right, but is brightness directly proportional to the apparent area we see?
During a solar eclipse, the moon passes between the sun and Earth, casting a shadow on the Earth's surface. This shadow blocks out some of the sunlight, causing a decrease in the overall brightness of the sun.
Yes, during a lunar eclipse, the Earth blocks the sunlight that would normally reflect off the moon's surface, causing a decrease in the moon's brightness.
Yes, during a total solar eclipse, the moon completely blocks out the sun's light for a short period of time, causing a sudden decrease in brightness during the day. This is known as "totality."
No, eclipses only cause temporary changes in brightness and do not have any long-term effects on the sun's overall brightness.
Yes, scientists often use eclipses as an opportunity to study the sun's atmosphere and other properties that are not normally visible due to the sun's brightness. This can provide valuable insights into the sun's behavior and help us better understand our solar system.
