Another Earth? Exoplanet Kelper-452b   32 comments

What Would it Be Like to Live on Earth’s Cousin?

The discovery of Kelper 452b was announced on 23/05/15, and is 1,400 Light years away.

An alien experience!

Exoplanet Kelper 452-b is 60% wider than Earth and approximately 5x as massive so much stronger surface gravity.

This provides for a great workout! For the manly among us this essentially means it will make you much stronger 🙂

For everybody chilling on this Earth cousin, the higher gravity would probably lead to significant body changes long term – e.g. becoming stockier built. This is probably not a plus if you’re already on the stocky side…you may become very short and squat…like a rotund garden gnome 😉

 

A Familiar Experience

As this world’s sun is roughly the same distance away as on Earth, the light factor would be much the same as on our home-world and Earth plants transported to its cousin-world could photosynthesis the same as on Earth.

 

 

 

 

 

So Kelper 452-b is similar to Earth but not the same. Its sun is 6 billion years old whereas our Sun is only 4.5 billion years old. Kelper 452-b’s sun is at a far more energetic life-stage therefore it is hotter. And it is about 10% larger and 20% brighter in the sky. Not bad for the sun tan then 😉

Kelper 452-b completes one orbit every 385 days so it’s year is only about 20 days longer than Earth’s. Pretty much home from home.
