How big is TrES-4b?

TrES-4b is 260,000 kilometers

A Journey to TrES-4b: The Gargantuan Exoplanet

Have you ever wondered how vast the universe is? Beyond our own solar system, there’s a whole wide cosmos waiting to be explored. Let’s embark on an exciting voyage to one of the most colossal planets out there, TrES-4b. TrES-4b is an extrasolar planet, which simply means it’s a planet outside our solar system. It’s not just any ordinary planet; it’s one of the largest exoplanets ever discovered! This gargantuan planet was discovered in 2006 and announced in 2007 by the Trans-Atlantic Exoplanet Survey (TrES).

How Big is TrES-4b?

To understand TrES-4b’s size, let’s compare it to some objects that we are familiar with:

  • TrES-4b is nearly 1.7 times the size of Jupiter, the largest planet in our solar system. If Jupiter were the size of a basketball, TrES-4b would be a massive exercise ball! - Despite its massive size, TrES-4b is less massive than Jupiter. This means it’s a lot lighter than you would expect for its size. It’s like a giant celestial balloon floating through space. - TrES-4b is even larger than some of the other colossal exoplanets like WASP-12b, WASP-17b, CT Chamaeleontis b, GQ Lupi b, and HD 100546 b.

Where Does TrES-4b Reside?

Now, let’s find out where this enormous planet is located. TrES-4b orbits a star called GSC 02620-00648, which is approximately 1,400 light-years away from us. This means that if you could travel at the speed of light, it would take you 1,400 years to get there! This star is located in the constellation Hercules, which is visible from many parts of the Earth during the summer months.

What’s So Special About TrES-4b?

Apart from its size, here are a few more interesting facts about TrES-4b:

  • TrES-4b is a ‘Hot Jupiter’. This means it’s similar to Jupiter in some ways but is much hotter because it orbits very close to its star. - Despite its close proximity to its star, TrES-4b is not very dense. It’s even less dense than water! If we could find a cosmic bathtub big enough, TrES-4b would float! - The planet was discovered using the transit method, where scientists observe a tiny dimming in the star’s light as the planet passes in front of it.

The Importance of TrES-4b

The discovery of TrES-4b helps us understand the vastness and variety of the universe. Every time astronomers find a new exoplanet, it gives us a glimpse into the potential for life beyond Earth and the formation of other solar systems. Each new find, like TrES-4b, brings us one step closer to understanding our place in the cosmos. So, the next time you look up at the stars, remember there’s a whole universe out there filled with incredible planets like TrES-4b, waiting for us to explore. Who knows what other fascinating discoveries are waiting for us in the deep, infinite cosmos?

Smaller By Category
Proxima Centauri
Proxima Centauri is known as being the closest star to Earth other than the Sun. Its name comes from the word "proximity". Proxima Centauri is a small red star. Unfortunately, it is so dim, you need a telescope to see it.
Wolf 359
Wolf 359 is a small red dwarf, dwarfed by normal stars. It is the sixth closest star to Earth, after the Sun, Proxima Centauri, Alpha Centauri A & B and Barnard's Star. Still, its magnitude is a dim +13.5.
Gliese 229B
Gliese 229B is a brown dwarf star. It orbits a larger dwarf star, which is Gliese 229A. Gliese 229B would be classified as a planet, but it is much denser than Jupiter, making its mass too large to be considered a planet.
Larger By Category
Distance from Earth to Moon
The Earth and the Moon here are not to scale. If the distance were a meter, Earth would be the size of a quarter, and the moon would be a pea.
Kapteyn's Star
Kapteyn's Star is only thirteen light-years away. Even so, its magnitude is +9, so you need binoculars to see it. Around 10,000 years ago, Kapteyn's Star was only seven light-years away!
Luyten's Star
Luyten's Star is a red dwarf star 12 light-years away from us. It is so close to the star Procyon that Procyon appears 10 times brighter to Luyten's Star than Sirius appears to us.
