The Sun
The layer at the center of the sun, where the nuclear fusion occurs and from where the sun gets its energy.
The term for the fact that Earth's orbit is slighting elliptical, not a perfect circle.
What is eccentricity?
When a celestial body orbits a larger body.
What is a natural satellite?
What is a terrestrial planet?
What is the Kuiper Belt?
Dark areas on the sun that are cooler than the gases around them.
What are sunspots?
March 21 and September 23; known for 12 hours of daytime and 12 hours of nighttime.
When are the equinoxes?
The moon doesn't have an atmosphere or water to "heal" scars of impacts.
Why does the moon have craters?
A planet that orbits the sun but does not dominate its own orbit.
What is a dwarf planet?
The hottest planet, with an extremely thick atmosphere full of carbon dioxide.
What is Venus?
The visible effects of space weather caused by solar
particles interacting with Earth's magnetic field.
What are auroras?
The solar intensity, which depends on the angle and amount of sun rays.
What is insolation?
It is a likely possibility that the moon was formed in this way: a Mars sized object knocked a piece of Earth off and combined with the pieces of the object to become the moon.
What is Giant Impact Theory?
The name of a meteoroid that has entered Earth's atmosphere and hit the surface of the Earth.
What is a meteorite?
Has the most tilted axis in the solar system.
What is Neptune?
What is the Convection Zone?
When the Earth comes between the Sun and the Full Moon.
What is a lunar eclipse?
When the Sun, Earth, and Moon are aligned along the same direction, causing the tides to be extra high and extra low. This also occurs during the new moon and full moon phases.
What is Spring Tide?
Large chunks of ice, dust, and rock that orbit the Sun in long, elliptical paths.
What are comets?
The amount of light reflected onto the moon from the sun.
This research method helps scientists analyze the Sun's chemical composition and activity through looking at the EM wavelengths emitted and absorbed by the sun.
What is spectroscopy?
The angle of insolation, the length of a day, and the seasons are all affected by this phenomenon.
What is the tilt of the Earth's axis?
The phase of the moon during a solar eclipse.
What is a New Moon?
The idea that the Solar System was formed after a massive star's death. When the star died, it sent out a huge explosion of matter into space which was brought back by gravity. The matter formed our Sun in the center, with a rotating disk of leftover gas and dust orbiting around it.
What is the Nebular Hypothesis?
When the amount of moon is increasing and the light part appears to be glowing.
What is a waxing moon phase?
