I started with an LLM, of course, but as soon as I got in touch with people from the field, I realized that AI often just 'wings it' or hallucinates.

Both scenarios are very interesting; I particularly like the one involving the Moon. However, everything in the story is already set up for a close flyby of a massive body—especially the main character's motivation. So, I now know I need to increase the planet's mass and bring the perigee...

The thing is, I need a timeframe of 12, maybe 15 months max from the first detection. I don't want years of humanity preparing and coming up with rescue scenarios. I want a maximum of 15 months of brutal waiting for the inevitable end. That’s why it’s a rogue planet and why the velocity is so...

So, if I tweak the parameters: A rogue planet with 80% of Earth's mass passes by our planet at a velocity of 200 km/s. Perigee is 10,000 km from the surface. That should be enough to trigger the first minor tremors and earthquakes several days before the flyby, followed by the total devastation...

It's a big body. It was originally supposed to be the size of Mercury. But it needs to be enlarged so that the first weak earthquakes can be felt at least a week before the flyby.

Most sci-fi premises are based on improbable events. What’s worse is that some creators simply throw logic and physics down the toilet. So, setting aside the improbability of a rogue planet's close flyby, my main focus is on a realistic description of the consequences. These will be described in...

What is more likely? That we will travel through time, or that two massive bodies will collide? And yet, how many wonderful stories have been written about these two improbabilities? Even greater magic would be required for two advanced civilizations to meet—considering the sheer size of the...

Thanks for the answers! So, the distance needs to be reduced (probably below 5,000 km) for the effects to remain the same. Except for the deflection of the planet towards the Sun... for that, a more massive planet would be needed. How massive exactly? At least half the size of Earth? Or would it...

Hello everyone, I’m looking for some feedback on the scientific realism of a specific catastrophic scenario for a story I’m working on. Here are the parameters: The Event: A Mercury-sized rogue planet passes Earth at a speed of 200 km/s. Closest Approach (Perigee): 70,000 km from Earth's...
