Mars' sparse atmosphere doesn't offer much protection from impacts by such objects as meteorites, asteroids, and comets. Alien conspiracy theory: Earth and Mars is the same planet; Humans, aka Mearthians, pretend it's two planets so they get more funding from the Galactic Union. Episode 52: Mars. . Monocular vs. Binoculars- Which One is Best for Stargazing. Ask: What do you think relative size means? Sometimes the planets are close together, and other times theyre on opposite sides of the Sun. Ask: Why do you think scientists find it helpful to use astronomical units? However, that doesn't happen very often. This is why the spacecraft sent to Mars are highly autonomous. Due to their orbital mechanics, the closest approach can occur a few days before or after opposition depending on whether Mars is moving away from the Earth and sun or towards the Earth and sun respectively, according to Celestron (opens in new tab). Close is a relative term. The numbers also assume that the two planets remain at a constant distance; that is, when a probe is launched from Earth while the two planets are at the closest approach, Mars would remain the same distance away over the 39 days it took the probe to travel. (Mercury) Which is the largest? If a media asset is downloadable, a download button appears in the corner of the media viewer.
