The new findings, published in The Astronomical Journal , include one such particularly rare planet. Officially named KIC-7340288 b, the planet discovered by Kunimoto is just 1 ½ times the size of Earth—small enough to be considered rocky, instead of gaseous like the giant planets of the Solar System—and in the habitable zone of its star.
"This planet is about a thousand light years away, so we're not getting there anytime soon!" said Kunimoto, a Ph.D. candidate in the department of physics and astronomy. "But this is a really exciting find, since there have only been 15 small, confirmed planets in the Habitable Zone found in Kepler data so far."
This may worth something:

New data from NASA's Juno spacecraft, which launched in 2011 and is orbiting the planet right now, suggests that water makes up about 0.25% of the molecules in Jupiter's atmosphere. That's about three times more than thought to be at the Sun.
"Just when we think we have things figured out, Jupiter reminds us how much we still have to learn," said Scott Bolton, Juno principal investigator at the Southwest Research Institute in San Antonio.

The discovery: Three "hot super-Earths" and a "warm Neptune" orbit a relatively nearby, bright star not unlike our own Sun, a new study suggests. One or more of these planets is so thoroughly cooked that its atmosphere appears to be leaking into space – in fact, that's how astronomers found these planets using a brand-new detection method.
Planets in Binaries: Formation and Dynamical Evolution - Astrobiology
Binary systems are very common among field stars. While this relatively small number of planets in binaries is probably partly due to strong observational biases.
There is, however, statistical evidence that planets are indeed less frequent in binaries with separations smaller than 100 au, strongly suggesting that the presence of a close in companion star has an adverse effect on planet formation.
It is indeed possible for the gravitational pull of the second star to affect all the different stages of planet formation, from proto-planetary disk formation to dust accumulation into planetesimals, to the accretion of these planetesimals into large planetary embryos and, eventually, the final growth of these embryos into planets.
And here's another article:
We Just Spotted a Potential New Planet Around the Sun's Neighboring Star | The National Interest
'Superpuff' alien worlds could be ringed giant planets just like Saturn | Space
All four outer planets in our solar system sport at least a few rings, but so far, we haven't observed any such features around exoplanets .
That's confusing, since these rings should be detectable with our current technology. A recent paper suggests that, actually, we've already seen ringed exoplanets, just in the form of strangely large, "superpuff" planets.
Except in rare cases, we don't get to take pictures of exoplanets directly. Instead, scientists have to infer the existence of these worlds through a series of lucky breaks . The most common method for spotting worlds around distant stars is to sit and stare at those suns for weeks on end, watching for any changes in brightness.
A planet could have been stolen from the solar system as it formed | New Scientist
The universe is a dangerous place. A new analysis has revealed that stars can frequently steal planets from each other in high-speed fly-bys – something that may even have happened in our own solar system.
Our understanding of how planets form was developed by looking out at our own cosmic neighbourhood, but these explanations can't account for some of the other star systems we have discovered, such as Jupiter-like planets orbiting extremely close to low-mass stars.

Here is how long it takes each of the planets in our solar system to orbit around the Sun (in Earth days):

A year on Earth is approximately 365 days. Why is that considered a year? Well, 365 days is about how long it takes for the Earth to orbit all the way around the Sun one time.
A year is measured by how long it takes a planet to orbit around its star. Earth orbits around the Sun in approximately 365 days. Credit: NASA/Terry Virts
