Another exoplanet near our Solar System

Although LHS 1140b has been discovered after the Trappist 1’s planets (which already come in the category of exoplanets), it is considered at the head of the rankings in Exoplanets.

LHS 1140b is 1.4 times the size of Earth and weighs 7 times that of Earth, showing that it is probably rocky with a dense iron core. The red dwarf it revolves around is benign and stable. LHS 1140b is 10 times more closer to its star than Earth is from the Sun, but the planet is not scorched because only half the amount of light, compared to our Sun, reaches the planet.

The planet also lies in the Goldilocks zone of it’s solar system, thus stating that liquid water, if present, will remain in liquid form, and won’t turn to ice or gas.

The planet is 40 light years away from Earth in the constellation of Cetus, the Sea Monster.

Yay for another exoplanet that we don’t have the capability to reach currently. Maybe sometime in the future, if we are able to travel at the speed of light, or find a mode of transport capable of leaping through space.

Stunning images of the TRAPPIST-1 star system

As you can recall, the discovery of TRAPPIST-1 system was made using Spitzer Space Telescope in combination with ground-based telescopes. Curious about the TRAPPIST system, Kepler spacecraft was made to collect data on the star’s minuscule changes in brightness due to transiting planets, so as to refine the previous measurements of six planets, and know the orbital period & mass of the seventh planet. (By late May, the routine processing of the data will be completed and the fully calibrated data will be made available at the public archive)

The observation period for the Kepler spacecraft was 74 days, also known as the K2 Campaign 12. This is the longest, nearly continuous set of observations of TRAPPIST-1 yet, and provides researchers with an opportunity to further study the gravitational interaction between the seven planets, and search for planets that may remain undiscovered in the system.
