Tools of Astronomy
These two characteristics are used to classify electromagnetic radiation.
Wavelength and Frequency
It's the percentage of incoming sunlight that reflects from the Moon's surface; only about 7 percent.
Albedo
Kepler's 1st law demonstrates that each planet has an elliptical orbit of unique size and shape with this celestial body at one focus.
The Sun
It's the brightes planet in Earth's night-time sky.
Venus
It's an object that due to its own gravity, has a spherical shape, orbits the Sun, is not a satellite and has not cleared the area of its orbit of smaller debris.
Dwarf planet
This type of telescope uses mirrors to focus visible light.
Reflecting telescope
It's the state at which the Moon's orbital and rotational periods are equal.
Synchronous rotation
Galileo's discovery of this planet's moons proved that not all celestial bodies orbit the Earth.
Jupiter
It's the closest planet to the Sun and has the largest day-night temperature difference of all planets in our solar system.
Mercury
They are small, icy bodies that have highly eccentric orbits around the Sun.
Comets
This type of telescope uses lenses to focus visible light.
Refracting telescope
The length of time it takes for the Moon to go through a complete cycle of phases.
Lunar month
The period when the Sun is overhead at the farthest distance either north or south of the equator.
Solstice
High concentrations of carbon dioxide in the atmosphere of this planet inhibits infrared radiation from escaping and keeps the surface extremely hot.
Venus
Gas and dust from which stars and planets form
Interstellar cloud
It's a technique that uses images from several telescopes to produce a single image.
Interferometry
List 3 reasons why the Earth's moon is unique compared to the moons of other planets.
1. It's the largest compared to the radius and mass of the planet it orbits
2. It has a solid rocky body.
3. It's orbit is farther from Earth relative to the distance of many moons from the planets they orbit.
The motion of a planet moving in the opposite direction of the normal direction of planetary motion as observed from Earth.
Retrograde
List the terrestrial planets
Mercury, Venus, Earth, and Mars
Object that collided and merged to form other various objects in the solar system.
Planetesimal
It's made up from all types of electromagnetic radiation arranged according to wavelength and frequency.
Electromagnetic spectrum
List the phases of the moon, in order as they appear beginning wieht the New Moon and Ending with the New Moon
1. New Moon 2. Waxing Crescent 3. First Quarter 4. Waxing Gibbous 5. Full moon 6. Waning Gibbous 7. Third Quarter 8. Waning Crescent
The closest point in the Moon's elliptical orbit to the Earth.
Perigee
List the gas giant planets.
Jupiter, Saturn, Uranus, and Neptune
List the 5 dwarf planets in our solar system as limited by the IAU.
Pluto, Eris, Ceres, Makemake and Haumea
