Evolving Earth: Solar System Environment Over Time

AI Thread Summary
The discussion focuses on the long-term changes in Earth's environment as it orbits the galaxy, emphasizing that these changes are influenced by the solar system's passage through varying density regions and galactic structures. It highlights the effects of density waves in spiral arms and the oscillation through the galactic plane on environmental conditions. Additionally, interactions with nearby stars can lead to perturbations in the Oort cloud, altering radiation levels and gravitational dynamics. These factors collectively suggest significant environmental shifts over extensive time scales. Understanding these influences is crucial for comprehending Earth's future in the broader context of the solar system's evolution.

Will Earth's, our solar systems environment, change over large time scales ?
i am not asking about solar or Earth (local) changes.

Yes, as our solar system orbits about the galaxy, it enters regions of higher/lower density (e.g., oscillating through the galactic plane, density waves through the spiral arms). And then there are events like interactions with nearby stars (e.g., Oort cloud pertubations, changes in radiation levels, gravitational interactions).

Thread 'Asteroid 2024 YR4 has a 1% risk of a multi-megaton impact in 2032 (now ruled out)'

Asteroid, Data - 1.2% risk of an impact on December 22, 2032. The estimated diameter is 55 m and an impact would likely release an energy of 8 megatons of TNT equivalent, although these numbers have a large uncertainty - it could also be 1 or 100 megatons. Currently the object has level 3 on the Torino scale, the second-highest ever (after Apophis) and only the third object to exceed level 1. Most likely it will miss, and if it hits then most likely it'll hit an ocean and be harmless, but...
