We say 'at the moment' because the obliquity changes over time, although very, very slowly. Earth's Obliquity Today Today, on April 10, 2024 at noon, Earth's axial tilt, or mean obliquity was 23.43625° or 23°26'10.5".
WebWe show that large-amplitude, high-frequency obliquity oscillations on Earth-like exoplanets can suppress the ice-albedo feedback, increasing the outer edge of the habitable zone. We restricted our exploration to hypothetical systems consisting of a solar-mass star, an Earth-mass planet at 1 AU, and 1 or 2 larger planets. ... WebMay 30, 2010 · The high-obliquity hypothesis would allow for a fully functional hydrological cycle and long-lived open seas; however there is currently minimal evidence to support this hypothesis (26). The normal fluctuations in Earth’s obliquity are seen in Figure 5, but if the obliquity was higher at the time that ice sheets were present it would possibly ...
