My Notes, From A Ravenclaw (Year 1)
These are my notes for all classes through year 1. There are 7 course in the first year. Charms, History of Magic, Herbology, Potions, Transfiguration, DADA, and Astronomy. I will add as I am able. Please check back for new content.
Please keep in mind, these are only major points and not to be substituted for the actual lessons!
Astr 101 Week 5
Named after the powerful and mighty
Roman god of the sky, Jupiter is the biggest planet in our solar system.
It is fifth from the Sun, right behind the Asteroid Belt.
It is the third brightest, after our Moon and Venus
It has a very strong gravity, much
stronger than Earth. Its exact mass is unknown, but it is approximately
twice the mass of all the other planets' masses combined. However the
Sun still weighs much more than Jupiter.
It can make a complete rotation in nine hours and fifty five minutes.
Jupiter's atmosphere is made up of mostly hydrogen and helium. Together, this makes up 99 percent of the atmosphere.
Jupiter has a banded atmosphere. The dark belts show the low pressure regions, whilst the lighter zones show high pressure regions.Due to the rotation of the planet, the bands wrap around the entire
planet, which makes the weather almost constantly the same within a
The gigantic red spot is a pile of winds, ones quite like a hurricane
here on Earth. It was discovered by the famous astronomer Robert Hooke
in the mid-17th century.
several layers of elements that make up the interior of the planet. The
core is made up of rocky material. Above the core is an element called
liquid metallic hydrogen. This layer is the source of Jupiter's magnetic
field. This layer may contain some helium and ice. The outermost layer
is made up of hydrogen and helium, which goes from liquid form to a
gassy form as it gets closer to the surface and the atmosphere.
Jupiter has 67 moons.They are Ganymede, Io, Callisto, and Europa. All four of these moons are
referred to as the Galilean moons, because the astronomer Galileo had
discovered them in 1610. Ganymede is the largest of the four moons with
the size of about Mercury. However, it has half the mass of the smallest
planet. Io is special because it is the only celestial body other than
Earth to have active volcanoes. Its atmosphere is full of sulfur dioxide
snowfields, so the moon is full of fire and ice. Callisto is full of
craters dented in its surface. Europa is barely dented with craters, but
it is thought that the moon may contain an ocean beneath the surface,
which could support life.
Jupiter's faint rings are made up of dust coming from the planet's moons as they orbit around the giant planet.
