Bulan: Perbedaan antara revisi

|''Nilai maksimum'' diberikan berdasarkan pada scaling of the brightness from the value of −12.74 given for an equator to Moon-centre distance of 378 000 km in the NASA factsheet reference to the minimum Earth–Moon distance given there, after the latter is corrected for Earth's equatorial radius of 6 378 km, giving 350 600 km. The ''minimum value'' (for a distant [[new moon]]) is based on a similar scaling using the maximum Earth–Moon distance of 407 000 km (given in the factsheet) and by calculating the brightness of the [[earthshine]] onto such a new moon. The brightness of the earthshine is {{nowrap|[ Earth [[albedo]] ×}} {{nowrap|([[Earth radius bumi]] /}} Radius of [[orbit Bulan]])² ] relative to the direct solar illumination that occurs for a fullbulan moonpurnama. ({{nowrap|Earth albedo {{=}} 0.367}}; {{nowrap|Earth radius {{=}} (polar}} radius × equatorial {{nowrap|radius)^½ {{=}} 6 367 km}}.)

| The range of angular size values given are based on simple scaling of the following values given in the fact sheet reference: at an Earth-equator to Moon-centre distance of 378 000 km, the [[Angular diameter| angular|ukuran sizeangular]] is 1896 [[arcsecond]]s. The same fact sheet gives extreme Earth–Moon distances of 407 000 km and 357 000 km. For the maximum angular size, the minimum distance has to be corrected for Earth's equatorial radius of 6 378 km, giving 350 600 km.
