TrES-4b is an extrasolar planet, and one of the largest exoplanets ever found, after WASP-12b, WASP-17b, CT Chamaeleontis b (though the latter may be a brown dwarf) and GQ Lupi b.
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.
Is Mercury smaller than Pluto?
Mercury is the smallest planet in the solar system. (Pluto used to hold the title, but it was downgraded to a dwarf planet.) Although its surface resembles our moon, the tiny planet has a density that rivals Earth itself.
Is there a super Earth?
The Solar System contains no known super-Earths, because Earth is the largest terrestrial planet in the Solar System, and all larger planets have both at least 14 times the mass of Earth and thick gaseous atmospheres without well-defined rocky or watery surfaces; that is, they are either gas giants or ice giants, not …
What 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.
Is Sun a planet?
Of the objects that orbit the Sun directly, the largest are the eight planets, with the remainder being smaller objects, the dwarf planets and small Solar System bodies.

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 Pluto smaller than Russia?
Russia has a bigger surface area than Pluto.
Pluto’s surface area is 16.7 million square kilometers. Russia’s surface area is 17,098,242 sq km.
Why is Pluto a dwarf planet but not Mercury?
The International Astronomical Union (IAU) downgraded the status of Pluto to that of a dwarf planet because it did not meet the three criteria the IAU uses to define a full-sized planet. Essentially Pluto meets all the criteria except one—it “has not cleared its neighboring region of other objects.”
What is the smallest planet in the universe?
The smallest planet in our solar system and nearest to the Sun, Mercury is only slightly larger than Earth’s Moon.
Can Super Earth support life?
Super-Earths are real and they could be an even better place to live than Earth. A super-Earth is a planet that’s similar to Earth, but larger. Astronomers are discovering they may be one of the most common planets in our galaxy. These planets can be almost double Earth’s radius and up to 10 times more massive.
Is there a planet made of diamond?
NASA has taken a closer look at 55 Cancri e, an exoplanet that earned the nickname “diamond planet” due to research that suggests it has a carbon-rich composition.
Is the diamond planet real?
In October 2012, it was announced that 55 Cancri e showed evidence for being a carbon planet. It has eight times the mass of Earth, and twice the radius. Research indicates that the 2,150 °C (3,900 °F) planet is “covered in graphite and diamond rather than water and granite”.
Which planet would float in water?
Saturn could float in water because it is mostly made of gas.
What planet is the coldest?
Neptune, being the eighth planet in our solar system and therefore the one furthest from the sun, has the coldest average temperature (around -214°C). On the other hand, Uranus being the 7th planet farthest from the sun, holds the record for the coldest temperature reached, with a record of -224°C.
