¡Estoy felicísimo! ¡no quepo en mí de alegría! Ayer designaron un asteroide con mi nombre. ¡Ya estoy en las estrellas! (más de lo que ya estaba, quiero decir ;-) ). ¡Muchas gracias a Rainer Kresken, el descubridor del asteroide, por su inmensa generosidad!

In February, the James Webb Space Telescope will briefly be able to observe asteroid 2024 YR4, which currently has a 4 per cent chance of hitting the moon in 2032. Depending on what it sees, the odds of collision could drastically increase

☄️ 40 000 near-Earth asteroids discovered!

Thankfully, none of them are cause for concern for the foreseeable future, but ESA's planetary defence teams are keeping a watchful eye on the skies.

We hear you, #CopernicusEU Sentinel-6B! The Inuvik Satellite Station in Canada has received the first signals from the satellite. The orbit has been reached, and telemetry has begun to arrive at ESA's mission control in Germany!
Mission confirmed ✅

#CopernicusEU Sentinel-6B is now in orbit and ready to begin its Launch & Early Operations phase with @operations.esa.int. The satellite is ready to continue a decades-long mission to track the height of the planet’s seas – a key measure of climate change.

Sure, you have family issues, but at least none of your siblings slammed into you at 18,000 kilometers per hour and sent your shattered pieces flying off into space with similar orbital elements.

I mean, probably.

Asteroid 2025 FA22 will safely pass Earth on 18 September 2025 at 07:41 UTC (09:41 CEST). It is between 130 and 290 m across and at its closest point to our planet, it will be just over twice as far away as the Moon.
