And this will remain alike for quite a while. Although a couple of closer approaches to Saturn (1.015 AU on 3 June 2011 and 1.93 AU around 1 October 2168) and Jupiter (0.889 AU on 15 January 2025, 0.771 AU on 21 February 2155, and 1.17 ± 0.03 AU in May–July 2214) are going to happen, the orbit of 39P/Oterma keeps its overall characteristics at least until the beginning of the 24th century: The semi-major axis will stay in the span of 7.0 to 7.8 AU, with the perihelion distance slowly increasing to 6.1 AU while the aphelion distance stays in the range of 8.1 to 9.4 AU, i.e. the orbit is again framed by Saturn's orbit on the outside and Jupiter's orbit in the inside. The period of revolution is always between 18.3 and 21.7 years.
