How far is the farthest exoplanet from Earth?
Astronomers have discovered one of the most distant planets known, a gas giant about 13,000 light-years from Earth, called OGLE-2014-BLG-0124L. The planet was discovered using a technique called microlensing, and the help of NASA’s Spitzer Space Telescope and the Optical Gravitational Lensing Experiment, or OGLE.
What are the nearest and farthest discovered exoplanets?
As of September 2020, the nearest known exoplanet is Proxima Centauri b, which was discovered with the radial velocity method and is about 4 light-years away. The farthest known exoplanet is SWEEPS-4b, which was discovered with the transit method and is about 27,700 light-years away.
What is the hottest exoplanet in the universe?
KELT-9b
One such planet, KELT-9b, is an ultrahot Jupiter that resides 670 light-years from Earth. It weighs about three times the mass of Jupiter and boasts surface temperatures of 7,800 degrees Fahrenheit (4,300 degrees Celsius). This makes KELT-9b the hottest exoplanet so far discovered. It’s even hotter than some stars.
How far can a telescope see?
The Hubble Space Telescope can see out to a distance of several billions of light-years. A light-year is the distance that light travels in 1 year.
What is the closest exoplanet to Earth?

What is the hottest exoplanet ever?
Astronomers announce the discovery of bloated gas giant KELT-9b, the hottest “hot Jupiter” exoplanet known, which sizzles as it wheels around its massive primary star.
Which habitable planet is closest to Earth?
The closest habitable planet to Earth is Gliese 581 c. It was discovered in 2007. It is at a distance 20 light years from earth. Although this is far in earth terms, it is relatively close in astronomical distances.
Which planet is closest to the Sun?
Mercury is the closest planet to the Sun. It’s orbit is very eccentric (i.e. non-circular) and Mercury comes to within 46 million km from the Sun at it’s closest point and 69.8 million km at it’s furthest point. Click Here To See Where Mercury Is Now.
