In 2019, NASA's Transiting Exoplanet Survey Satellite (TESS) discovered a super-Earth and two mini-Neptunes orbiting a faint, cool star about 73 light-years away in the southern constellation of Pictor.Scientists have discovered a super-Earth, named TOI-715 b, located within the “conservative” habitable zone of a nearby red dwarf star. This revelation has ignited the astronomical community with the potential of uncovering conditions that are suitable for life a mere 137 light-years from Earth.Astronomers have discovered a “super-Earth,” or a world larger than our planet, orbiting a star about 137 light-years away. A second planet, thought to be the size of Earth, may also be orbiting the same star.
How big is the super-Earth : The term "super-Earth" is also used by astronomers to refer to planets bigger than Earth-like planets (from 0.8 to 1.2 Earth-radius), but smaller than mini-Neptunes (from 2 to 4 Earth-radii).
Is life possible on super-Earth
A "super-Earth", a planet larger than Earth but smaller than Neptune. American space agency NASA has discovered a "super-Earth", a planet that could potentially support life. It is located 137 light-years away.
How long would it take to go 1400 light-years away : 26 million years
So 1,400 light-years equals about 8.2 quadrillion miles. If we took one of our fastest probes to the planet, New Horizons, which is currently traveling about 36,000 miles per hour (50,000 km/h), it would take well over 26 million years to reach our destination.
Recently discovered super-Earth might be habitable — and it could have a sibling. TOI-715 b is particularly intriguing to researchers as a potentially rocky planet at just the right distance from its star that it could host water on its surface. NASA's exoplanet hunting missions such as Kepler and Transiting Exoplanet Survey Satellite (TESS) have helped astronomers realize that such planets are surprisingly very common in the Milky Way: A third of all exoplanets are super-Earths.
How long is 13 billion light years away
We know that light takes time to travel, so that if we observe an object that is 13 billion light years away, then that light has been traveling towards us for 13 billion years. Essentially, we are seeing that object as it appeared 13 billion years ago.They concluded that the Universe is at least 250 times larger than the observable universe, or 7 trillion light-years across. But, ultimately, science has no reliable estimate of the actual size of the entire Universe.Because the star runs cool, this super-Earth can orbit closer and still be within the solar system's habitable zone, which is "the distance from the star that could give the planet the right temperature for liquid water to form on its surface," and therefore sustain life. 26 million years
So 1,400 light-years equals about 8.2 quadrillion miles. If we took one of our fastest probes to the planet, New Horizons, which is currently traveling about 36,000 miles per hour (50,000 km/h), it would take well over 26 million years to reach our destination.
How far is TOI-715 b from Earth : About 137 light-years away
About 137 light-years away, the super-Earth TOI-715 b orbits a red dwarf sun. The exoplanet has a mass of 3.02 Earths and was first found in 2023.
Can we see Kepler-452b : It's a star that's similar to our own sun, but it's too faint for us to see from Earth without a telescope. Kepler-452 is about 1,800 light years away, which means it currently would take a spacecraft about 30m years to travel there. At least one planet is orbiting the star: it's called.
Can humans reach Kepler-452b
While Kepler-452b may appear a tantalizing target for the upcoming NASA missions, it is highly unlikely humans ever will step foot on Kepler-452b, thanks to the 1,400 light-years it will take them to reach there. About 137 light-years away
About 137 light-years away, the super-Earth TOI-715 b orbits a red dwarf sun. The exoplanet has a mass of 3.02 Earths and was first found in 2023. The same star system may also hold a smaller, nearly Earth-sized planet.Cosmologists aren't sure if the universe is infinitely big or just extremely large. To measure the universe, astronomers instead look at its curvature. The geometric curve on large scales of the universe tells us about its overall shape. If the universe is perfectly geometrically flat, then it can be infinite.
How much is 1 light year : 5.88 trillion miles
Light-year is the distance light travels in one year. Light zips through interstellar space at 186,000 miles (300,000 kilometers) per second and 5.88 trillion miles (9.46 trillion kilometers) per year.
