On April 13, 2029, asteroid Apophis (370m wide) will pass Earth
closer than GPS satellites — 31,000 km away.
3 billion people will be able to see it with the naked eye.
ISS is visible to the naked eye at mag −5.9 — brighter than any star.

Apophis (370m wide) passes Earth at 37,371 km on April 13, 2029 — inside the GPS satellite ring (20,200 km shows in blue). 3 billion people will see it naked-eye. Drag the 3D scene. The trail shows the full hyperbolic trajectory.
I compute reentry heating profiles for a living. VøidSignal is what that looks like as art.
I'm an aerospace engineering student grinding through student debt with one plan: make space
so beautiful and so understandable that people can't look away.
Every animation here is built from real orbital mechanics. Every satellite has a real story.
Every number is physics, not fiction. I calculate reentry heating loads. I model orbital decay.
And now I'm showing you what that actually looks like.
Space is the most extraordinary thing our species has ever done.
Most people have never been shown how extraordinary it really is. That's what this is for.

// WHY VOIDSIGNAL
The void between satellites and the Earth is where the real story lives.
Signals sent into the dark that nobody heard. Spacecraft that orbited in silence for decades.
The Kármán line where pilots become astronauts. This project exists to transmit those signals
to people who've never heard them.
Follow @VøidSignal on X — 40 days of daily space
animations, each built from real physics, posted with the engineering explained.
Every dead satellite still orbiting is a ghost — a signal from the void.
Launched by a real aerospace student with actual orbital mechanics knowledge
and a concerning amount of student debt. Not a trader. Not an influencer.
Someone who debugs FEM meshes at 2am and also launched a token.
