The Solar System
Mercury, Venus, Earth, and Mars are all examples of this kind of planet.
Terrestrial
This theory describes the origin of the universe, suggesting it began with a massive explosion.
The Big Bang Theory
Kepler's First Law states that the orbit of a planet around the sun is this shape.
Ellipse
The Earth is closest to the Sun during this season in the Northern Hemisphere.
Winter
The Sun generates energy through this process, where hydrogen nuclei combine to form helium.
Nuclear Fusion
This part of the electromagnetic spectrum is able to be seen by the human eye and consists of the colors of the rainbow.
Visible Light
This type of planet is primarily composed of hydrogen and helium gases and lacks a solid surface.
Jovian (Gas Giant)
This hypothesis explains the formation of the solar system from a cloud of gas and dust.
The Nebular Hypothesis
According to Kepler's Second Law, a planet moves faster in its orbit when it is closer to this.
The Sun
The gravitational pull of this celestial body is the primary cause of tides on Earth.
This process, essential for plant life on Earth, is powered by sunlight.
Photosynthesis
These waves have the longest wavelengths in the electromagnetic spectrum and are used for communication.
Radio Waves
This dwarf planet, once considered the ninth planet of our solar system, is found in the Kuiper Belt.
Pluto
According to the Nebular Hypothesis, this force caused the gas and dust to collapse into a spinning disk.
Gravity
This term refers to the point in a planet's orbit where it is farthest from the Sun.
Aphelion
This season occurs when the Northern Hemisphere is tilted toward the Sun.
Summer
This layer of the Sun is where nuclear fusion occurs, producing the Sun’s energy.
The Core
These highly energetic waves have the shortest wavelengths and are used in medical imaging.
Gamma Rays
This region of our solar system lies between the orbits of Mars and Jupiter and is home to millions of rocky bodies.
Asteroid Belt
In the Nebular Hypothesis, the center of the collapsing nebula forms this body, which will eventually ignite to become a star.
Protostar
If a planets orbit is 10 million kilometers (c) and the semi-major axis is 25 million kilometers (a) what is the planets eccentricity?
O.4
When it’s winter in the Northern Hemisphere, this season is occurring in the Southern Hemisphere.
Summer
The Sun is the primary source of this for Earth's atmosphere, driving weather, climate, and the water cycle.
Energy
In the electromagnetic spectrum, as the wavelength decreases, this property of the wave increases.
Frequency
This spherical shell is believed to surround our solar system and is where the Sun's gravity ends.
The Oort Cloud
This is responsible for clearing the remaining gas and dust after the planets and other celestial bodies form.
Solar Wind
According the Kepler's Third Law, this planet has the slowest revolution of all the planets in our solar system.
Neptune
During neap tides, the gravitational pull of the Sun and Moon partially cancels out, as they are at right angles with the Earth, resulting in this kind of tidal range.
Energy from the Sun's core passes through this zone where it can take thousands of years to reach the next layer.
Radiative Zone
Prolonged exposure to this type of electromagnetic radiation can increase the risk of skin cancer.
Ultraviolet (UV) Light
