Celestial Bodies 1
A celestial body of hot gas that gives off heat and light
What are Stars?
Was the first to use a telescope to observe space. Found craters on the Moon, spots on the Sun, & 4 of Jupiter’s moons
Who is Galileo?
The 3rd Planet from the Sun?
What is Earth?
The type of star that will burn for the longest (about 100 billion years)
What are Low mass stars?
The darker patches on the surface of the sun that indicate cooler areas
What are Sun Spots?
The closest star to us
What is the Sun?
Observed the sky with his naked eye and thought of a more simple model. Thought the sun was at the centre and the earth revolved around it while rotating on its axis
Who is Copernicus?
The closest planet to the Sun
What is Mercury?
A cloud of dust and gases in outer space where all stars are born
What are Nebulas?
Occasional, extremely violent eruptions of gas ejecting material from the sun’s surface out into space
What are Solar Flares?
A celestial body that orbits a star, is large enough that its own gravity holds it together, & is the only body occupying its orbital path
What are Planets?
Designed the reflecting telescope- better observations. Used mathematical formulas to explain why celestial bodies orbit each other (gravity)
Who is Newton?
The closest jovian planet to the Sun
What is Jupiter?
The stage of a Intermediate mass star which follows a White Dwarf
What is a Black Dwarf?
Large loops of super-hot gas that extend out from
the Sun’s surface
What are Solar Prominences?
A Celestial body that revolves around a planet
What are Moons?
Saw that patterns of stars didn’t change. Thought earth was fixed (didn’t move). Thought the sun and other planets orbited the earth
Who is Aristotle?
The planet that once was classified as a planet, but now classified as a Dwarf planet.
What is Pluto?
The stage that follows a Red supergiant in a High Mass star
What is a Supernova Explosion?
Hot gases around the Sun get ejected in a sudden burst
What are Solar Winds?
An enormous collections of gases, dust, and stars held together by gravity
What is a Galaxy?
Observed the movement of planets and tested mathematical formulas to make models of their motion. Found that planets must orbit in ellipses instead of circles
Who is Kepler?
The farthest planet away from the Sun
What is Neptune?
a large sphere of tightly packed material with an extraordinary amount of gravitational pull, created when a high mass star collapses into itself
What is a Black Hole?
Energy emitted from the sun in the form of electromagnetic radiation
What is Solar Radiation?
