   Longer-lived stars are therefore more likely to have planets with life, just because more time is allowed for life to develop and fill ecological niches. Cooler stars have longer lifespans than hotter stars. Liquid water is necessary for life. For a planet/moon/asteroid to be considered habitable, it must orbit in a zone where liquid water is ...

   Then have the class help you calculate the inner (1 x 0.7) and outer (1 x 1.5) reaches of the Suns goldilocks zone, adding them to the axis. Ask the students which planets are inside the habitable zone. The figure below shows you the habitable zone for the Sun and the first four planets in our solar system:

   known as the habitable or ‘goldilocks’ zone. Not too hot and not too cold, the perfect condition for water, which is essential to life. In this activity we will look at some other stars which all have planets orbiting them too. We will find out if any of the planets orbiting these other stars are in the habitable zone as well, seeing if

   2 days ago · For instance, our planet is habitable since we know that we have a biosphere of living things at the surface. But what other kinds of planets or places on planets might be habitable? An important first step in answering that question is to think about liquid water. All of life as we know it needs liquid water to survive.

   Planets around large stars have to be far from their star and may not have enough time to develop life before the star dies. PLANETS . ORBITS . How and where a planet orbits its star is very important for its habitability. Habitable planets are likely found in the Goldilocks zone, meaning they’re just the right distance from their star for ...

   Is a planet a habitable planet?

   • It is not thorough enough to simply say that if a planet is a certain distance from its central star (i.e., if it’s in the Goldilocks Zone), then it is habitable. What if the orbit is highly elliptical (not very circular)?

   What makes a planet habitable?

   • An important first step in answering that question is to think about liquid water. All of life as we know it needs liquid water to survive. So, one important characteristic that might make a planet habitable is if it has liquid water at its surface like we do here on Earth. The Earth is 93 million miles from the Sun.

   What is the habitability zone in astrobiology?

   • This online interactive allows students to change the settings of a planet’s size, distance to star, age, and type of star it orbits in order to understand the habitability zone. The habitability zone is a very important concept in astrobiology and is tied to CLQ1.2 in terms of the creation of Earth as a habitable environment.

   Could a moon make a planet habitable?

   • We also have to think about the importance of moons for making a planet habitable. Could having a moon make a planet more likely to have life? Computer modeling shows that having a large moon could be beneficial for a planet to have life because the planet doesn’t wobble as much.

Also, when nutrients are spread so thin that they are hard to obtain, such as on a gas planet, life cannot exist. All solid planets & moons have the same general chemical makeup, so nutrients are present. Those with a
