The planets that have been discovered so far range in size and composition. There are so-called hot Jupiters—which, as their name suggests, are gaseous worlds that orbit close to the fires of their parent planet. Others are smaller gas worlds, similar in size to Neptune.

On Monday, NASA confirmed that the confirmed total of exoplanets, planets beyond our solar system, exceeded the 5,000 mark, adding 65 confirmed exoplanets in the latest batch to the NASA Exoplanet Archive.
When is a planet not a planet? When it's actually a star

The astronomers saw that while the estimates for diameters of the vast majority of stars were very similar for both missions, some stood out as pretty discrepant. In general, ones that were off were for stars that were very far away, more than about 4,000 light years.
New Planet-Hunting Technologies: NASA's Roman Mission Could Snap First Image of a Jupiter-Like World
Roman will use its Coronagraph Instrument – a system of masks, prisms, detectors, and even self-flexing mirrors built to block out the glare from distant stars and reveal the planets in orbit around them – to demonstrate that direct imaging technologies can perform even better in ...

Confirmed: There are now 5,000 planets outside our solar system
After 30 years of peering into space through the eyes of NASA telescopes, the space agency has announced that there are a confirmed 5,000 planets beyond our solar system.
NASA shared in its release that the 5,000 contains a variety of planets, including rocky worlds like Earth, gas giants larger than Jupiter, and "hot Jupiters" in scorchingly close orbits to their stars.
