Label the parts of the Surface of the Sun.
We use these units to measure distance in Space: , , , , and
What is the definition of AU?
The astronomical unit (AU) is a unit of length, roughly the distance from the Earth to the Sun.
The astronomical unit (AU) is a unit of length, roughly the distance from the Earth to Mars.
Define a Light-Year:
The distance light travels in a year
a unit of astronomical distance equivalent to the distance that light travels in two years, which is 9.4607 × 1012 km (nearly 6 trillion miles)
Define Scientific Notation:
Scientific notation is a mathematical expression used to represent a decimal number between 1 and 10 multiplied by ten, so you can write large numbers using less digits.
Scientific notation is a mathematical expression used to represent a decimal number between 1 and 100 multiplied by ten, so you can write large numbers using less digits.
Define Parralax:
the position or direction of an object appears to differ when viewed from different positions, e.g., through the viewfinder and the lens of a camera.
the position or direction of an object appears to stay the same when viewed from different positions, e.g., through the viewfinder and the lens of a camera.
Define Triangulation:
Uses simple geometry to determine distance in space by using a baseline and two angles
Uses complex geometry to determine distance in space by using a baseline and three angles
