Online Calculators since 2009
The Stars Illumination Calculator will calculate the:
Calculation Parameters: None of values can be zero
|Illumination of the unknown star (b2) [lux]|
|Illumination of the unknown star calculation|
|b2 = b1 ∙ 100.4 ∙ (m1 - m2 )|
b2 = ∙ 100.4 ∙ ( - )
b2 = ∙ 100.4 ∙
b2 = ∙ 10
b2 = ∙
|Stars Illumination Calculator Input Values|
|Apparent magnitude of the reference star (m1) |
|Apparent magnitude of the unknown star (m2) |
|Illumination of the reference star (b1) [lux]|
Please note that the formula for each calculation along with detailed calculations are available below. As you enter the specific factors of each stars illumination calculation, the Stars Illumination Calculator will automatically calculate the results and update the Physics formula elements with each element of the stars illumination calculation. You can then email or print this stars illumination calculation as required for later use.
