WebNov 24, 2015 · For the comet with a period of t = 83 years then the semi major axis a3 = 832. Squaring and taking the cube root gives approximately a = 19 AU. The perihelion distance P = a(1 − e) and the aphelion distance A = a(1 + e) where e = 0.875 is the eccentricity. This gives a perihelion distance of 2.375AU and an aphelion distance of … WebFeb 13, 2024 · There are two distances. The first is aphelion which refers to the farthest distance Mars can be from the Sun whereas perihelion refers to the closest the planet can be to the Sun. At aphelion, the planet is …

WebApr 4, 2024 · The astronomical formula for calculating Mars’ eccentricity is given as: e = ( D a − D p) ( D a + D p) Where, D a = aphelion distance between Mars and the Sun D p = perihelion distance between Mars and the Sun Therefore, Mars perihelion distance = 206,700,000 Km and Mars aphelion distance = 249,200,000 Km. WebThe semi-major axis is one-half the sum of the aphelion and perihelion, so we have a = 1 2(aphelion+perihelion) aphelion = 2a−perihelion. a = 1 2 ( aphelion + perihelion) aphelion = 2 a − perihelion. Substituting for the values, we found for the semi-major axis and the value given for the perihelion, we find the value of the aphelion to be 35.0 AU. WebThe closest opposition is when the Earth is at aphelion and Mars is at perihelion, so the distance is 1.38 - 1.02 = 0.36 AU. The furthest opposition is when the Earth is at perihelion and Mars is at aphelion, so the distance is 1.67 - 0.98 = 0.69 AU. So it is almost twice as far away at the furthest opposition as at the closest. philpots school
