The exoplanet, TOI-715 b, is about one and a half times the width of Earth.

Unfortunately super earths aren't viable for us. They would both have crushing gravity and that gravity would make rockets leaving the planet impossible. Fuel to weight ratio would ensure no one could ever leave.

So they could have organisms that are much stronger than us, but they could also be a lot smarter and a lot more cooperative with each other. But they would be unable to leave their planet because of the lack of chemical rockets and would need to come up with much more ingenious ideas while we could just hurl metal rods from the God's and annihilate them.
