Neerudesse

Neerudesse is a fictional planet featured in the science fiction novel "The Martian" by Andy Weir. It is not a real celestial body. In the story, Neerudesse is a planet located in the Andromeda galaxy, approximately 2.5 million light-years from Earth. It is depicted as a gas giant, similar in composition to Jupiter. The planet's primary role in "The Martian" is as a potential destination for an emergency mission to rescue the protagonist, Mark Watney.

The narrative describes Neerudesse as a world of extreme conditions. It possesses a dense atmosphere composed mainly of hydrogen and helium, with trace amounts of other gases. Its gravity is significantly higher than Earth's, and it experiences powerful storms and radiation. Despite its inhospitable nature, the plot involves a hypothetical scenario where a spacecraft could utilize a gravitational assist from Neerudesse to alter its trajectory and return to Earth. This concept of using a planet's gravity to slingshot a spacecraft is a real astronomical phenomenon known as a gravitational slingshot or gravity assist. The fictional details of Neerudesse, while rooted in scientific principles, are tailored to serve the plot's requirements within the context of "The Martian."
