Length of year (single revolution around the sun): 365.26 days.Length of solar day (single rotation on its axis): 23.934 hours.Statistics about Earth's orbit, according to NASA: Our planet is a bit closer to the sun in early January and farther away in July, although this proximity has a much smaller effect on the temperatures we experience on the planet's surface than does the tilt of Earth's axis. Earth's orbit is not a perfect circle, but rather a slightly oval-shaped ellipse, similar to the orbits of all the other planets in our solar system. This means the Northern and Southern hemispheres will sometimes point toward or away from the sun depending on the time of year, and this changes the amount of light the hemispheres receive, resulting in the changing seasons.Įarth happens to orbit the sun within the so-called ' Goldilocks zone,' where temperatures are just right to maintain liquid water on our planet's surface. It takes Earth 23.934 hours to complete a rotation on its axis and 365.26 days to complete an orbit around the sun - our days and years on Earth are defined by these gyrations.Įarth's axis of rotation is tilted in relation to the ecliptic plane, an imaginary surface through the planet's orbit around the sun. Caltech manages JPL for NASA.While Earth orbits the sun, the planet is simultaneously spinning around an imaginary line called an axis that runs through the core, from the North Pole to the South Pole.

Data are archived at the Infrared Science Archive housed at Caltech/IPAC. Spacecraft operations are based at Lockheed Martin Space Systems Company, Littleton, Colorado.

Science operations are conducted at the Spitzer Science Center at Caltech in Pasadena. NASA's Jet Propulsion Laboratory, Pasadena, California, manages the Spitzer Space Telescope mission for NASA's Science Mission Directorate, Washington. The system was named for the TRAPPIST telescope. The TRAPPIST-1 system has been revealed through observations from NASA's Spitzer Space Telescope and the ground-based TRAPPIST (TRAnsiting Planets and PlanetesImals Small Telescope) telescope, as well as other ground-based observatories. The star itself, an ultra-cool dwarf, would appear about three times larger than our own sun does in Earth's skies. TRAPPIST-1e would appear about the same size as the moon and TRAPPIST1-c is on the far side of the star. In this view, the planets in the sky correspond to TRAPPIST1e (top left crescent), d (middle crescent) and c (bright dot to the lower right of the crescents).

One of the unusual features of TRAPPIST-1 planets is how close they are to each other - so close that other planets could be visible in the sky from the surface of each one. If the night side is icy, the day side might give way to liquid water in the area where sufficient starlight hits the surface. This artist's concept allows us to imagine what it would be like to stand on the surface of the exoplanet TRAPPIST-1f, located in the TRAPPIST-1 system in the constellation Aquarius.īecause this planet is thought to be tidally locked to its star, meaning the same face of the planet is always pointed at the star, there would be a region called the terminator that perpetually divides day and night.
