A study published in the journal Earth and Planetary Science Letters posits that Mars formed in what today is the Asteroid Belt, roughly one and a half times as far from the Sun as its current position, before migrating to its present location.
NASA has stated that it’s quite likely that our solar system is home to a massive, distant ninth planet. Its existence could shed light on some burning questions about the cosmos.
Last year, the existence of an unknown planet in our Solar system was announced. However, this hypothesis was subsequently called into question as biases in the observational data were detected. Now astronomers have used a novel technique to analyze the orbits of the so-called extreme trans-Neptunian objects and, once again, they point out that there is something perturbing them: a planet located at a distance between 300 to 400 times the Earth-Sun separation.
An unknown Mars-to-Earth-mass planet may lurk in the outer reaches of the Solar System.
Space physicists say that they now have a treasure trove of information about how Pluto’s atmosphere interacts with the solar wind.
