Kepler-22

-
Kepler-22 is a star, located in the northern constellation of Cygnus. The star is orbited by a planet that is located within the star's habitable zone. The estimated distance of Kepler-22 is approximately 620 light-years away from our solar system.Kepler-22 is slightly smaller and cooler then the Sun. 
On December 5th, 2011, scientists from the Kepler mission announced that a possible Earthlike planet - Kelper-22b. It’s super-Earth (size of 9 Earths) that could be covered in super ocean.

The habitable zone is the region in which liquid water could exist on a planet's surface. Liquid water is a key ingredient to life, so planets found within this zone are more likely to be habitable worlds. However, planets must also be the right size, and Kepler-22b is too big. Planet’s orbital period is around 300 days which is similar to our environment.

Kepler-22b's first transit in front of its host sun was observed on Kepler's third day of scientific operations in mid-2009. Kepler-22b's third transit was detected in late 2010. The Spitzer Space Telescope provided more data that confirmed Kepler-22b's transits. On December, 2011, the confirmation of the existence of Kepler-22b was announced.

    Why does the size of the planet matter in whether it's habitable or not?

TRAPPIST-1

TRAPPIST-1  is a cool red dwarf star  with seven known exoplanets . It lies in the constellation Aquarius  about  40.66 light years  away from Earth .  The system is far too faint to be seen with the unaided eye.  Around a star which is 12 times less massive than the Sun and only slightly larger than Jupiter, there are at least seven planets in orbit. They  have sizes and masses comparable to the Earth and Venus.  Because we know the distance of the planets to their star, and the temperature of the star, we can deduce that they receive an amount of light that is similar to many of the planets in the Solar system, from Mercury to Mars.  Three or four of them reside within their star's habitable zone, meaning they orbit at the right distance to support liquid water on their surfaces .   TRAPPIST stands for "Transiting Planets and Planetesimals Small Telescope," which is actually a pair of telescopes: one at the European Sout...

The Sun

Image
The sun is an ordinary  star , one of about 100 billion in our   galaxy , the Milky Way. The sun has extremely important influences on our planet: It drives weather, ocean currents, seasons, and  climate , and makes plant life possible through  photosynthesis . Without the sun’s heat and light, life on Earth would not exist. The Sun moves around the Galactic Center  of the Milky Way , at a distance of 26,660 light years . From Earth, it is  about 8 light minutes  away. It’s diameter  is about 109 times that of Earth . It’s mass  is about 330,000 times that of Earth, making up about 99.86% of the total mass of the Solar System.  Roughly three-quarters of the Sun's mass  consists of hydrogen (~73%); the rest is mostly helium (~25%), with much smaller quantities of heavier elements, including oxygen , carbon , neon , and iron . The sun was born about 4.6 billion years ago. Many scientists think the sun and the rest of the solar system ...

Cat’s eye nebula 🌌

Image
The Cat’s Eye Nebula, also known as NGC 6543, is a planetary nebula located 3,000 lightyears away in the constellation Draco.  Planetary nebulae are one of the final stages of a Sun-like star, as they run out of fuel and begin losing their outer layers into space.   The Sun will end its life in similar fashion in about five billion years. It will first expand into a red giant with a diameter about 100 times greater than it originally was. At the centre of the Cat's Eye Nebula is a dying Wolf Rayet star.  The star is believed to have originally had a mass of around 5 times that of the Sun and is now estimated to have only over one solar mass.  Wolf-Rayet stars are hot (25-50,000+ degrees K), massive stars (20+ solar mass) with a high rate of mass loss. Th e type was first distinguished in 1867 by the French astronomers  Charles-Joseph-Étienne Wolf and   Georges-Antoine-Pons Rayet.
