💚 In our investigation, we’ll be measuring distance in light-years. From our last lesson, what is a light year?
INVESTIGATION - an attempt to find out about something
DATA - observations or measurements recorded in an investigation
In today’s investigation you will collect data about the distance from Earth to different stars, like the sun and also the stars in the constellation Pegasus!

In today’s investigation you will collect data about the distance from Earth to different stars, like the sun and also the stars in the constellation Pegasus!
Pegasus
When people look at Pegasus (PEG-uh-sus), they usually notice four stars that make a large square shape. This is called the Great Square of Pegasus. Pegasus is named after a famous animal from Greek mythology, a magical flying horse. In North America, we see Pegasus in the fall, in September it is high in the sky.
Names of the four stars in the great square of Pegasus:
Alpheratz (AL-fer-rats)
Beta Pegasi (BAY-tuh PEG-a-see)
Algenib (al-JEN-nib)
Markab (MAR-kab)

Directions: Finding Distances of Stars from Earth:
Login to the Sim, Patterns of Earth and Sky by clicking on the website https://apps.learning.amplify.com/patternsofearthandsky/
Login to your Amplify account.
Once in the Sim…
Turn constellations ON at the top of the Sim.
In System View - click and drag your Earth so it is between Pegasus and the Sun.
In System View - Click on the word “Pegasus.” This will highlight it in yellow.
Click on NOON for your time. In Sky View - click on the Sun and record the distance to the sun.
Click on MIDNIGHT.
Click the stars in the four corners of Pegasus and record their distance in the table.
