    Retrograde
AI Thread Summary
2009 MS9 is confirmed to have a prograde orbit, with an inclination of 68.07923°. Orbits with inclinations greater than 90° are classified as retrograde, while those between 0° and 90° are prograde. The information was sourced from the JPL Small-Body Database Browser. Despite some visual perspectives suggesting a retrograde appearance, the inclination clearly indicates its prograde status. This clarification aids in understanding the dynamics of extreme trans-neptunian objects.

I'm constructing a theory on the origin of extreme trans-neptunian objects.

Can anyone tell me if 2009 MS9 is prograde or retrograde in its orbit? (and show me where you found this information out). I can't for the life of me find it anywhere.

Thanks.

2009 MS9 is prograde in its orbit. Inclinations greater than 90° describe retrograde orbits, thus, an inclination of between 0° and 90° means the orbiting body has a prograde orbit. 2009 MS9 has an inclination of 68.07923°.

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...
