Spaceflight 🚀The warning time ⚠️ is unlikely to be more than a few months. Impacts 💥 from objects as small as 50 meters in diameter 📏, which are far more common, are historically extremely destructive regionally <a href="https://en.wikipedia.org/wiki/Asteroid_impact_avoidance#Deflection_efforts" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://en.wikipedia.org/wiki/Asteroid_impact_avoidance#Deflection_efforts</a><a href="https://spacey.space/tags/AsteroidThreat" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#AsteroidThreat</a> <a href="https://spacey.space/tags/AsteroidDeflection" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#AsteroidDeflection</a>
