Which planet is the biggest in the universe?
In our Solar System, Jupiter is the largest planet we have, but what’s the upper limit to planetary size? Jupiter may be the largest and most massive planet in the Solar System, but adding more mass to it… [+] If you get too much mass together in a single object, its core will fuse lighter elements into heavier ones.
What planet is bigger than Jupiter?
The observations revealed that KPS-1b is slightly larger than Jupiter – 1.03 Jovian radii– and more massive than its equivalent planet in our solar system ‒ 1.09 Jovian masses ‒ orbiting a star that is slightly smaller than our Sun, 0.91 our Sun’s radii in size.
What is the smallest planet ever discovered?
As of February 2013 it is the smallest planet discovered around a main-sequence star, with a radius slightly greater than that of the Moon and slightly smaller than that of Mercury.

Is any planet bigger than the sun?
To begin with planets, as that is the easiest question to answer, there are no planets bigger than the Sun or even close to the size of the Sun. At about 13 times the mass of Jupiter a planet becomes what is referred to as a “brown dwarf”.
What is the most beautiful planet in the universe?
The planet Saturn is probably the best known and most beautiful planet in the Solar System.
Is the sun a planet?
The sun and moon are not planets when you consider the objects in space they orbit. For the sun to be a planet, it would have to orbit another sun. Although the sun is in a orbit, it moves around the center of mass of the Milky Way galaxy, not another star.
Which planet would float in water?
Saturn could float in water because it is mostly made of gas.
What planet is closest to the sun?
Mercury—the smallest planet in our solar system and closest to the Sun—is only slightly larger than Earth’s Moon. Mercury is the fastest planet, zipping around the Sun every 88 Earth days.
Which is the brightest planet?
Venus is brightest at what’s called greatest illuminated extent, or greatest brilliancy. It happens when Venus is relatively near Earth, and when telescopes show it in a crescent phase, like a tiny crescent moon. At such times, you can see Venus in the daytime.
What is the least known planet?
Scientists have found the smallest known planet — smaller than Mercury, the smallest planet in Earth’s solar system. A team of scientists including two Yale University astronomers has discovered the smallest planet yet detected.
Which is the smallest planet in our galaxy?
Mercury
How big is the smallest planet?
The smallest planet in regards to both mass and volume is Mercury — at 4,879 km across and 3.3010 x 1023 kg, this tiny world is nearly 20 times less massive than Earth, and its diameter is about 2½ times smaller. In fact, Mercury is closer in size to our Moon than to Earth.
