Who discovered the pink planet?
NASA
A 160 million-year-old alien planet has been discovered by NASA, along with stunning images. Using the infrared Subaru Telescope in Hawaii, astronomers snapped a photo of the breathtaking exoplanet, orbiting a star that was named GJ 504 in 2013.
Who discovered the 1st exoplanet?
On 9 January 1992, radio astronomers Aleksander Wolszczan and Dale Frail announced the discovery of two planets orbiting the pulsar PSR 1257+12. This discovery was confirmed, and is generally considered to be the first definitive detection of exoplanets.
What is the pink planet called?
GJ 504b
Named GJ 504b, the planet is made of pink gas. It’s similar to Jupiter, a giant gas planet in our own solar system. But GJ 504b is four times more massive. At 460°F, it’s the temperature of a hot oven, and it’s the planet’s intense heat that causes it to glow.

Is there a planet on GJ 504B?
Labeled NASA composite image, combining Subaru images of GJ 504 using two near-infrared wavelengths (orange, 1.6 micrometers, taken in May 2011; blue, 1.2 micrometers, April 2012). Once processed to remove scattered starlight, the images reveal the orbiting planet, GJ 504b. NASA artist’s impression of GJ 504 b.
How old is GJ 504B?
This peculiar Jovian planet, known as GJ 504 b, is approximately four times the size of Jupiter. The solar system of the planet is deemed to be around 100-200 million years old, relatively young (in cosmic time).
What is the distance between GJ 504B and the star?
GJ 504b lies at a projected distance of 43.5 AU from its star; the actual distance depends on how the system tips to our line of sight, which is not precisely known.
What is the estimated mass of Gliese 504B?
Estimated mass of Gliese 504 b depends on the value of its age, which is poorly known. The discoverers adopted age value 0.16 +0.35 −1.0 M Jup. In 2015, other astronomers obtained age value 4.5 +2.0 −1.5 Gyr, which corresponds to 20-30 M Jup. In this case, the object is a brown dwarf rather than a planet. In 2017, an intermediate age value 2.5 +1.0
