Context: It is hypothesized that a fifth force of nature can be observed as interplanetary interactions. Here, we look at potential evidence that Mars acts on Earth according to the expression when Mars-Earth distance is less than both Mars-Sun and Mars-Venus distances; C is some positive constant;
is Earth’s latitude from Mars; T and M are Mars’ sidereal rotation period and mass, respectively; and
,
, and
are unit vectors representing Mars’ north celestial pole, Earth’s north celestial pole, and Mars’ position from Earth, respectively. A full description can be found here: Mathematical Model Used to Predict Interplanetary Phenomena
To test whether Mars influences Earth’s atmosphere, we utilized a comprehensive dataset covering mean daily U-wind speeds from 1981 to 2023, totalling 15,695 observations [Ref1]. These values were averaged over all latitudes, longitudes, and atmospheric pressure levels.
On any given day, there are four major bodies that could be closer to Mars than Earth. These are: the Sun, Venus, Mercury, and the Moon. We divided wind data into two groups: days when Earth was closer to Mars than the Sun or Venus, and all other days. For convenience, define S as a sphere of radius Earth-Mars distance centred on Mars. The value when S contains the Sun and/or Venus. Otherwise,

Figure 2 compares U-wind speeds with U(Mars). It shows the relationship between mean daily U-wind speeds and U(Mars) over the period from 1981 to 1 March 2025. In many instances, peaks and troughs in U(Mars) appear to correspond with similar patterns in U-wind speeds, including a noticeable time lag. The panels extending beyond 2024 into 2035 provide projected values of U(Mars), suggesting future trends that could potentially affect U-wind speeds.

The observed correlation between the relative positions of Earth and Mars and Earth’s atmospheric conditions presents an intriguing finding. Our analysis indicates that when Mars-Earth distance is less than Mars-Sun and Mars-Venus distances (S = 1), there is a statistically significant difference in mean daily U-wind speeds compared to other days (S = 0). This finding is supported by the results of the two-sample T-test which showed a p-value of , indicating a highly significant difference between the two groups.
Moreover, the relationship between U-wind speeds and the hypothesized U(Mars) suggests a potential dynamic interaction. The regression analysis substantiates this connection, with an value of 0.767 and a statistically significant coefficient for U(Mars)/C (
). This result highlights a clear long-term daily relationship between U-wind speeds and U(Mars), reinforcing the hypothesis of a planetary influence on terrestrial atmospheric dynamics, and warranting further investigation into the mechanisms underlying this phenomenon.
Despite these compelling findings, it is crucial to approach these results with caution. Several potential confounding factors could influence these observations, including solar activity, the gravitational effects of other planets, and varying atmospheric conditions on Earth. These factors need to be meticulously controlled in future studies to isolate the specific impact of Mars’ relative position on Earth’s atmospheric behavior.
Additionally, the dataset spans over four decades (1981-2023), providing robust temporal coverage. However, more rigorous statistical testing and the incorporation of additional datasets are necessary to validate these findings further. For instance, employing Granger causality tests could help refine our understanding of the causal dynamics between planetary positions and atmospheric conditions.
Future research should aim to extend the analysis by incorporating more comprehensive astronomical data and exploring the influence of other planetary bodies. By isolating and understanding these complex interactions, we can advance our knowledge of how extraterrestrial factors might influence terrestrial weather patterns, thereby enhancing our predictive capabilities for future atmospheric phenomena.
