How many exo-planets are there?
As of October 2021, astronomers have discovered over 4,500 confirmed exoplanets. This number continues to grow rapidly as new telescopes and technology are developed to detect more of these planets outside of our solar system.
How many exoplanets do we know of?
Now we know of 861 exoplanets, with several thousand awaiting confirmation
Is there a similar planet from the earth in the Universe?
There are planets outside our solar system known as exoplanets that might have Earth-like conditions, but none have been found that are identical to Earth. The search for Earth-like exoplanets continues using telescopes and technologies to explore the vast universe.
Which planet do most known extra solar planets least resemble?
Most known exoplanets least resemble Earth, as many of them fall into categories such as gas giants or "hot Jupiters," which are significantly larger and have different atmospheric compositions compared to our planet. Additionally, many exoplanets orbit very close to their stars, leading to extreme temperatures and conditions that are not conducive to life as we know it. These factors contribute to a stark contrast between these exoplanets and Earth.
Why couldn't astronomers detect these planets before?
Astronomers struggled to detect certain exoplanets in the past due to limitations in observational technology and methods. Many planets are obscured by the brightness of their host stars, making them difficult to see directly. Additionally, earlier detection techniques, such as radial velocity and transit methods, were less sensitive to smaller planets or those in distant orbits. Advances in telescope technology and observational techniques, such as improved imaging and space-based instruments, have since enhanced our ability to identify and study these elusive planets.
How many exoplanets were recently discovered?
about 403.
How many planets are in the galaxy way?
We hardly know yet. Planets other than those in our own solar system (called "extrasolar" planets or "exoplanets") have only been discovered in the last ten years or so. About a thousand are known, but astronomers feel there must be many, many more.

Earth is one of many planets. There are 8 planets in our own solar system and over 400 exoplanets found so far.
Does earth really have a sister panet?
There is currently no confirmed sister planet to Earth. However, astronomers have discovered many exoplanets in other solar systems that share similar characteristics with Earth, such as being rocky and located in the habitable zone of their star.
