TRAPPIST-1 Solar System Comparison. This diagram compares the TRAPPIST-1 planet system with Earth's solar system. The size of Earth's sun is shown with regard to the red dwarf star, TRAPPIST-1. The position of the seven planets around TRAPPIST-1 are shown in relation to Mercury's orbit around the sun.

Last week's lunar eclipse wasn't just a show for Earthlings, NASA's MESSENGER mission was also watching from Mercury, 66 million miles away.

First image obtained from Mercury orbit

First Image Ever Obtained from Mercury Orbit

A little over a week before NASA's MAVEN spacecraft fired its rockets to successfully enter orbit around Mars, MESSENGER performed a little burn of its own – the second of four orbit correction maneuvers (OCMs) that will allow it to remain in orbit around Mercury until next March. Although it is closing in on the end…

At 5:20 am EDT on Mar. 29, 2011, MESSENGER captured this historic image of Mercury. This image is the first ever obtained from a spacecraft in orbit about the Solar System's innermost planet. Over the subsequent six hours, MESSENGER acquired an additional 363 images before downlinking some of the data to Earth. The MESSENGER team is currently looking over the newly returned data, which are still continuing to come down.

A Mercury Transit Sequence   : This coming Monday Mercury will cross the face of the Sun as seen from Earth. Called a transit the last time this happened was in 2006. Because the plane of Mercury's orbit is not exactly coincident with the plane of Earth's orbit Mercury usually appears to pass over or under the Sun. The above time-lapse sequence superimposed on a single frame was taken from a balcony in Belgium shows the entire transit of 2003 May 7. The solar crossing lasted over five hours…

In his theory of general relativity, Einstein showed that mass warps space. + how it affects mercury

Finally. Seriously, why is Mercury a planet when it's smaller than Pluto? Someone tell me why we're being the equivalent of racist against Pluto.<< VIVA LA PLUTOOOOOO
