Mars has quite literally put on a happy face. The Martian crater Galle is famous for internal markings that resemble a smiling, winking face. These features were first noticed in images taken by the Viking Orbiter in the 1970s. Later, the Mars Global Surveyor (MGS), which orbited Mars from 1996 to 2006, captured the well-known image of what is now called the Happy Face Crater. This crater and its iconic appearance were formed purely by chance billions of years ago, when a city-sized asteroid struck the Martian surface. Impact craters are common on all rocky planets and moons in our Solar System, with the Moon and Mercury showing the highest numbers. Earth and Venus would display many more craters as well, if not for the effects of weathering, erosion, and geological activity. transunion credit freeze

I ran SETI@home many years ago. You had to have a screensaver anyway, and I seem to recall that the screensaver portion looked super cool and science-y, so it was trendy even if you weren’t particularly enthusiastic about the actual project.
Habitability in this usage means "a place where humans can live, either with or without technological assistance". In terms of temperature, this means the range of temperatures where machinery can reliably function. Of the temperatures found in the universe, this machinery-functionable range is actually extremely narrow
There’s not really any data other than a rough distance from its star. The atmosphere could be thick enough and with the right combination of greenhouse gases that the temperature at the equator is 23°C year round. We do know that it’s only receiving ~30% of the energy from its star as earth does from the sun, which is what they’re basing the low temperature estimates on.
And it’s not like once we have the technology needed to travel 146 light years that we couldn’t do something insane like deploy mirror-film solar cells or something to capture extra heat in orbit around the planet and warm the entire planet and terraform it for our usage.
