WHAT is the definition of orbit
the curved path of a celestial object or spacecraft around a star, planet, or moon, especially a periodic elliptical revolution.
which planet is actual a drarwf planet
pluto
change in appearance of the moon as viewed from the Earth due to relative positions of the Moon, Earth, and Sun.
MOON PHASE
The actual amount of light (radiation) a star emits. Also called luminosity.
Absolute Magnitude
The lighter shadow that is lighter than the umbra
penumbra
A giant group of stars, dust, and gas that are held together by gravity.
galaxy
which planet is closest to the sun
VENUS
moon phase that occurs when the Moon is between the Earth and the Sun and cannot be seen from Earth.
New moon
How bright a star appears from Earth.
Apparent Magnitude
the darker middle part of the shadow
umbra
Planet that can support life. Third from the sun in our solar system.
Earth
a star that is the source of light and heat for the planets in the solar system. It is 93,000,000 miles from the Earth.
THE SUN!!
describes the phases following a new moon as more of the lighted side becomes visible.
Waxing
The distance light can travel in one year (about 9.4 trillion km).
light year
What are the two kinds of solar eclipses?
partial and total
A giant ball of light that is located at the center of our solar system.
The sun
the closest planet to the Sun, very cold on one side and very hot on the other, smallest planet, and no moons.
Mercury
phase that occurs when the Moon's entire surface facing the Earth reflects light
Full moon
How hot the surface of a star is. Also tells the star's color and spectral class.
Temperature
The sun is completely blocked and on light from its rim can be seen.
Total eclipse
A rock, or Minor Planet orbiting the Sun.
Asteroid
the 2nd planet from Sun, covered with volcanoes, no moon, hottest planet, and rotates very slowly and backwards.
Venus
occurs when the Moon passes directly between the Sun and Earth, and casts a shadow over part of Earth.
Solar eclipse
Stars grouped together by they way the emit light. OBAFGKM. Also tells the star's temperature and color.
Spectral Class
the light from the sun's rim that can be seen during a total solar eclipse. Suns halo.
