WebJul 7, 2015 · In 2015, aphelion (or apoapsis) occurs at 19:40 Universal Time (UT)/3:40 PM EDT today, as we sit 1.01668 astronomical units (AU) from the sun. This translates to 152.1 million kilometres, or 94.5 ... The astronomical unit was originally conceived as the average of Earth's aphelion and perihelion; however, since 2012 it has been defined as exactly 149 597 870 700 m (see below for several conversions). [5] The astronomical unit is used primarily for measuring distances within the Solar System or around other stars. See more The astronomical unit (symbol: au, or AU or AU) is a unit of length, roughly the distance from Earth to the Sun and approximately equal to 150 million kilometres (93 million miles) or 8.3 light-minutes. The actual … See more A variety of unit symbols and abbreviations have been in use for the astronomical unit. In a 1976 resolution, the International Astronomical Union (IAU) had used the symbol A … See more With the definitions used before 2012, the astronomical unit was dependent on the heliocentric gravitational constant, that is the product of the gravitational constant, G, and the solar mass, M☉. Neither G nor M☉ can be measured to high accuracy separately, but the … See more The unit distance A (the value of the astronomical unit in metres) can be expressed in terms of other astronomical constants: See more Earth's orbit around the Sun is an ellipse. The semi-major axis of this elliptic orbit is defined to be half of the straight line segment that joins the perihelion and aphelion. … See more The book On the Sizes and Distances of the Sun and Moon, which is ascribed to Aristarchus, says the distance to the Sun is 18 to 20 times the distance to the Moon, whereas the true ratio is about 389.174. The latter estimate was based on the angle between the See more • Orders of magnitude (length) See more

WebFor Earth, the orbital eccentricity is only 0.017, so perihelion and aphelion are at 0.983 AU and 1.017 AU respectively. Thus, the change in flux from perihelion to aphelion would be only. Flux sun (perihelion)/Flux sun (aphelion) = (1.017 AU / 0.983 AU) 2 = (1.034) 2 = 1.070 and the consequent change in temperature is only
