Educator Guide: A Weird Solar System Cousin Makes Its Photographic Debut

star TYC 8998-760-1 with exoplanets

The star TYC 8998-760-1 (top center) was photographed with two giant exoplanets (arrows), the first time astronomers have directly imaged more than one planet orbiting a sunlike star. The bright spots above star TYC 8998-760-1 are other stars in the background.

About this guide

In this guide, students will examine a photograph of a distant solar system, learn how astronomers captured the image and learn about the system’s inhabitants. Students will then discuss units of measure and create a scaled drawing of the distant solar system.

This Guide Includes:

Capturing an exoplanet family portrait

Students will answer questions about the online Science News article “This is the first picture of a sunlike star with multiple exoplanets,” which describes a young solar system 300 light-years from our own. A version of the story, “A weird solar system cousin makes its photographic debut,” can be found in the August 29, 2020 issue of Science News.

Why use units

To determine the purpose of units in science, students will identify and compare the units used for common outer space measurements with units typically used for Earth measurements. Then, students will think about the importance of using standard units versus relative values when describing data before creating a scaled drawing of exoplanet distances.
