A growing body of research indicates that there are likely billion of Earth-like planets that we haven't yet discovered.

Nine years' worth of observations by the Hubble Space Telescope revealed about 10,000 galaxies in one of the deepest, darkest patches of night sky in the universe.
That means a rocky planet that's roughly the size of Earth. Scientists haven't exactly defined this size range, since they don't yet know how big rocky planets can be.
Not to change the topic here:
A stunning animation by a planetary scientist shows how huge our solar system is — and why that
Most models of the solar system aren't completely accurate, and there's a good reason for that.
It's not laziness or scientific misunderstanding - an accurate, to-scale portrayal of the solar system just wouldn't look that interesting. You have to zoom in to see what's going on.
James O'Donoghue, a planetary scientist at the Japanese space agency (JAXA) and formerly at NASA , recently ran into this problem. He created a series of animations that explore the difficulty of accurately depicting our solar system.
Scientists conclude planets possible around supermassive black holes – Astronomy Now
Theoreticians in two different fields defied the common knowledge that planets orbit stars like the Sun. They proposed the possibility of thousands of planets around a supermassive black hole.
“With the right conditions, planets could be formed even in harsh environments, such as around a black hole,” says Keiichi Wada, a professor at Kagoshima University researching active galactic nuclei which are luminous objects energized by black holes.

It sounds unbelievable, but a new study from Kagoshima University and the National Astronomical Observatory of Japan says that exoplanets – thousands of them – could be orbiting supermassive black holes.

The intriguing findings were announced by researchers at Kagoshima University and the National Astronomical Observatory of Japan on November 25, 2019. The new peer-reviewed study was published in The Astrophysical Journal on November 26, 2019.

Sunday night will be a gorgeous view of three bright planets — Jupiter, Venus and Saturn — equally spaced low in the southwestern sky shortly after sunset with a thin waxing crescent moon peering down at the trio from the upper left. Jupiter continues to draw ever closer to the sun and will be lost in the twilight glow by the middle of the month. It goes behind the sun (conjunction) on Dec. 27. Venus will be within just 2 degrees of Saturn (two thumb widths at arm's length) on Dec. 10 and 11.
Astronomy triple treat: Three planets will be visible this week | WAVY.com
You’re going to want to check out the night sky just after our early sunsets for the next couple of days. Three planets, Jupiter, Venus, and Saturn, will be in our southwest sky after sunset.
Venus is now going to enter our night sky as the second brightest object, following the moon for the months ahead. Jupiter has been in our sky for sometime, but is soon going to fall below the horizon with the setting sun making it impossible to see very soon.

The Planet Mercury Passes Across The Sun | Science Times
The tiny planet Mercury was seen traveling across the Sun in a beautiful entrance. Mercury is known as the smallest planet in the solar system (if only you agree that Pluto is not considered a planet) and is only a little bigger than the moon of the Earth.
It is also the nearest planet to the Sun, which means that it rotates much quicker than all the other worlds in the solar system.
