3I/ATLAS Comet's Earth Flyby: No Harm Expected
A comet named 3I/ATLAS recently flew by Earth at a distance of 269 million kilometres.
It has a gas plume that contains poisonous substances like cyanide.
Scientists wondered if any of this material could reach Earth.
While some particles might have been blown towards us by solar winds, the Earth's atmosphere would protect us by burning up any harmful particles before they reach the ground.
The comet is now heading towards Jupiter for its final rendezvous in our solar system.
So, even though the comet has some dangerous materials, we don't need to worry because our atmosphere keeps us safe.
3I/ATLAS comet flew by Earth at a distance of 269 million kilometres.
The comet has a gas plume containing cyanide and hydrogen cyanide.
Solar winds could have blown some material towards Earth, but the atmosphere would protect us.
Particles smaller than a micrometre are affected by solar radiation, while larger particles are not.
The comet is now heading towards Jupiter for its final rendezvous in the solar system.
