In this video from NASA, learn about the history of defining a planet, and examine how classification changes based on new knowledge. Our understanding of the solar system has evolved since the ancient Greeks, who first used the word planetes to distinguish the objects that moved against the backdro

Discover what happens at the outer edges of our solar system, where the solar wind interacts with interstellar space. The Interstellar Boundary Explorer (IBEX) is a mission to study the boundary between the solar system and interstellar space. Voyager 1 and 2 have provided some direct measurements f
Explore how astronomers and scientists use astronomical units to measure distances in the solar system in this video adapted from NASA. The astronomical unit (au) -- equal to the average distance from Earth to the Sun -- is a convenient unit of measure when talking about distances in the solar syste
Explore how human understanding of planetary orbits has changed throughout history in this video about Kepler's laws of planetary motion. Kepler's three laws of planetary motion accurately describe the elliptical orbits of objects around the Sun. This video presents the story of Johannes Kepler and
The solar system is our home. But what do we know about it? How big is it and how did it come into existence? Just watch the video! Author: Cornel Becheru Click here to see more videos: https://alugha.com/mysimpleshow
Discover how scientists compare the reflected red, blue, and green light from planets in our solar system to identify Earthlike planets beyond our solar system more easily. Carolyn Crow, a member of the Deep Impact science team, describes how the amount of green, blue, and red light reflected by pla
Discover how impact craters can provide insight into the history of the solar system in this video from NASA's Goddard Space Flight Center. Scientists compare impact craters that have changed over time with fresh craters to determine how landforms have evolved. The Linne crater on the Moon is a pris
Learn about seasonal changes on Pluto in this video adapted from NASA. Pluto is one of the largest members of the Kuiper belt, a region of small icy bodies in the outer solar system. Pluto is so tiny and distant that even images from the Hubble Space Telescope do not show much detail. Extensive comp
Learn about Neptune's gravitational effect on dust contained in the Kuiper belt and discover how it could help astronomers look for planets around other stars. This video from NASA explores the idea that if would-be alien astronomers were looking for planets around the Sun, they could potentially de
