The Counter-Earth is a hypothetical body of the Solar System that orbits on the other side of the solar system from Earth. A Counter-Earth or Antichthon (Greek: Ἀντίχθων) was hypothesized by the pre-Socratic Greek philosopher Philolaus (c. 470 – c.
There's been a hypothesis floating around for a few years that there might be a ninth planet in our Solar System—and it's not Pluto. Planet Nine is unnamed, unconfirmed, and unknown. We haven't been able to detect it, and we don't even know for sure that if we did spot it, it would even be a planet.
Unfortunately, the forces of gravity conspire to make this hidden planet idea completely impossible. Most importantly, when someone tells you there's a hidden planet on the other side of the Sun, just remember these words: No.
Since the Earth travels at almost 19 miles per second, or 67,000 miles per hour, two Earths smashing into each other would wipe out all life on each of them instantaneously. A second Earth wouldn't necessarily need to share our exact orbit, though.
Counter-Earth, also known as Halfworld, was an artificial planet located in the Keystone Quadrant. It was designed by High Evolutionary as a replication of Earth and was inhabited by Humanimals.
During the Crisis on Infinite Earths, Earth-One was destroyed. The New Earth that emerged after the Big Bang possessed elements of Earth-One's history, along with elements similar to that of Earth-Two, Earth-Four, Earth-S, and Earth-X.
The silhouette of the Biosphere 2 science complex1 dances on the horizon in the heat of the Arizona desert. The building, which is made entirely of glass and resembles a giant greenhouse, is home to a miniature Earth.
Kepler-452b (sometimes quoted to be an Earth 2.0 or Earth's Cousin based on its characteristics; also known by its Kepler Object of Interest designation KOI-7016.01) is a super-Earth exoplanet orbiting within the inner edge of the habitable zone of the sun-like star Kepler-452 and is the only planet in the system ...
NASA's TESS spacecraft found the two planets, which are slightly larger than Earth. Astronomers have spotted two "super-Earth" exoplanets orbiting within the habitable zone of a nearby star.
It wouldn't be good. At the Equator, the earth's rotational motion is at its fastest, about a thousand miles an hour. If that motion suddenly stopped, the momentum would send things flying eastward. Moving rocks and oceans would trigger earthquakes and tsunamis.
The falling trajectory of the earth around the sun, combined with earth's tilt, is what causes the different seasons. All the planets in our solar system are falling around the sun but have enough speed to not hit it.
Using data from NASA's Transiting Exoplanet Survey Satellite, scientists have identified an Earth-size world, called TOI 700 e, orbiting within the habitable zone of its star – the range of distances where liquid water could occur on a planet's surface.
(Editor's note: The Sun has no dark side.
TOI-5205b was discovered in data from NASA's alien planet-hunting Transiting Exoplanet Survey Satellite (TESS). TESS finds planets using the transit method. Whenever a planet passes in front of its parent star, that star's brightness slightly dips.
Astronomers have found an unusually large planet orbiting a small star, located about 280 light-years from Earth. The unexpected size of the newly discovered world, called TOI 5205b, has led researchers to call it the “forbidden planet.”
Planet Nine is a hypothetical ninth planet in the outer region of the Solar System. Its gravitational effects could explain the peculiar clustering of orbits for a group of extreme trans-Neptunian objects (ETNOs), bodies beyond Neptune that orbit the Sun at distances averaging more than 250 times that of the Earth.
For most space objects, we use light-years to describe their distance. A light-year is the distance light travels in one Earth year. One light-year is about 6 trillion miles (9 trillion km).
Scientists at NASA have recently announced that they found a planet that is almost identical (about 95%) to Earth's size and shape and has a rocky surface. Named TOI 700 e, this new planet orbits within its star's habitable zone, which also hints at the presence of water on its surface.
If a super-Earth is ejected from its star system and has a dense atmosphere and watery surface, it could sustain life for tens of billions of years, far longer than life on Earth could persist before the Sun dies.
Earth was a planet of Earth-15. The planet became known as a "dead Earth" following an event in 1986, and radioactive fallout was teleported there in 2018, but any remains of the planet were destroyed during the Anti-Monitor Crisis.
The name Earth derives from the eighth century Anglo-Saxon word erda, which means ground or soil, and ultimately descends from Proto-Indo European *erþō. From this it has cognates throughout the Germanic languages, including with Jörð, the name of the giantess of Norse myth.
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.
The term "super-Earth" refers only to the mass of the planet, and so does not imply anything about the surface conditions or habitability. The alternative term "gas dwarfs" may be more accurate for those at the higher end of the mass scale, although "mini-Neptunes" is a more common term.
