Reasons
Kepler-62f
✓
As its parent star is
a relatively quiet
star, and has less
mass than the Sun.
It can live up to a
span of about 30
billion years or so.
Kepler-168f
✓

the transit method,
along with four
additional planets
orbiting much
closer to the star.
Mercury
✓
are not in the
habitable zone
because they are
too close to the sun
to harbor liquid
water.
Kepler-442b
✓
This was
considered the
most-habitable
non-tidally locked
exoplanet
discovered. K-type
main-sequence
stars are smaller
than the Sun and
live longer,
remaining on the
main sequence 18
to 34 billion years
compared to the
Sun's estimated 10
billion.
Venus has a mean
surface
temperature of
462°C (863°F), the

result of a runaway
greenhouse in its
primarily carbon

atmosphere.
Guide Questions:
1. Compare the similarities and differences of basic features of
Earth to the other members of the solar system.
(Similarities) Venus and Mars are the most like Earth, but in different ways. In
terms of size, average density, mass, and surface gravity.
(Differences) It rotates on its axis every 24 hours (a day) and revolves around
the Sun every 365 days (a year). While the other planets like mars has 1day and
37mins.
2. Based on your comparisons, what makes the Earth a unique
planet and able to support life?
- Earth is unique because we have water that people need, Air atmosphere
that is made mostly of nitrogen and has plenty of oxygen for us to
breathe. The atmosphere and magnetic field help show the earth's surface
from harmful sun radiation.
