1. Mars verse earth lesson
Pick a "something" your satellite analyzed
and compare it to Earth's corresponding
meaning- Olympus Mons-Modis group
and a volcano on Earth
Maven-Martian escape velocity of gases
and Dr Rob total ozone mapping spectrometer for Earth
Curiostiy-compare to impact crater on Earth
Curiosity -compare to a rift on Earth
Titan-compare to Earth-why did nasa pick Titan
(encephalus)
or can do an exoplanet system
or a binary star system
or Gravity wave detectio
A super-Earth is an extrasolar planet with a mass higher than Earth's, but substantially below the
masses of the Solar System's ice giants, Uranus and Neptune, which contain 15 and 17 Earth
masses respectively.[1]
The term super-Earth refers only to the mass of the planet, and so does not
imply anything about the surface conditions or habitability. The alternative term gas dwarfs may be
more accurate for those at the higher end of the mass scale, as suggested by MIT professor Sara
Seager, although mini-Neptunes is a more common term.
An exoplanet (UK: /ˈɛk.soʊˌplæn.ɪt/, US: /ˌɛk.soʊˈplæn.ɪt/)[3]
or extrasolar planet is a planet outside
of our solar system that orbits a star. The first scientific detection of an exoplanet was in 1988, but
the first confirmed detection did not come until 1992. As of 8 September 2017, there are
3,667 planets in 2,747 systems, with 616 systems having more than one planet.[4]
HARPS (since 2004) has discovered about a hundred exoplanets while the Kepler space
telescope (since 2009) has found more than two thousand. Kepler has also detected a few
thousand[5][6]
candidate planets,[7][8]
of which about 11% may be false positives.[9]
In several
cases, multiple planets have been observed around a star.[10]
About 1 in 5 Sun-like stars[a]
have an
"Earth-sized"[b]
planet in the habitable zone.[c]
Assuming there are 200 billion stars in the Milky
Way,[d]
one can hypothesize that there are 11 billion potentially habitable Earth-sized planets in the
Milky Way, rising to 40 billion if planets orbiting the numerous red dwarfs are included.[11]
The least massive planet known is Draugr (also known as PSR B1257+12 A or PSR B1257+12 b),
which is about twice the mass of the Moon
