Why does the Sun shine brighter some days? [duplicate] 1) The sun seems brighter (more dazzling) if there is more scattering in the atmosphere The sun would actually look very small to us in the sky if there were no atmosphere (it's the same angular size as the moon) and most of the brightness seen in the direction of the sun is from small deflection rayleigh scattering
How come the Suns gravity can hold distant planets in orbit, but . . . First, we should speak of acceleration rather than force, because like I said earlier all objects at a given distance from the Sun experience different forces but the same acceleration You ask "how come the Sun is strong enough to keep the distant planets in orbit but I don't fall into it?"
Why does the Sun always rise in the East? - Physics Stack Exchange The Sun does not rise, it is the horizon that goes down You say that Sun rises in the East (with a certain degree of oscillations due to the tilt of the axis) just because the Earth spins from West to East The revolution affects the difference between sidereal time and solar time, and makes the solar day $\approx 4$ minutes longer If the Earth spinned in the opposite direction the Sun would
How much lux does the Sun emit? - Physics Stack Exchange I want to know how much lux the sun emits on a bright day - I don't mean when one stares directly at the sun, but rather when one walks casually outside when the sun is shinning brightly Now the
photons - Light formed by the sun? - Physics Stack Exchange The photons take thousands of years to "fight" their way to the surface of the Sun, but then escape into space as visible or near visible photons at the speed of light I am really confused about how the sun produces light I understand that through nuclear fusion, energy is formed, but isn't this energy in the form of thermal and gamma photons?
Why does Sun appear white at noon? - Physics Stack Exchange The Sun appears white at noon because the sunlight reaching the observer maintains its full spectral composition, meaning that all visible wavelengths arrive in nearly equal proportions
What is actually meant by sun set and sun rise times, when taking . . . If this is the case, then when we read things like what time sun sets and rises on websites, books, calendars, other official times, et al… does that mean when we see for example ‘sun set at 18:35’ is the time denoting the actual sun set taking into account of the mirage or what is visible to us
What determines the surface temperature of the sun? The core temperature of the sun is on the order of 15 million degrees kelvin while its surface temperature is around 6000k What are the main factors which determine the surface temperature of the
