As an expert in the field of astronomy, I can tell you that determining the "oldest planet" in the universe is a complex task fraught with uncertainties. The universe itself is estimated to be around 13.8 billion years old, and the oldest stars we've observed are of a similar age, formed shortly after the Big Bang. Planets, however, are thought to form around these stars, which means the oldest planets would also be quite ancient.
The reference you provided suggests that a Jupiter-sized planet was discovered around a sun-like star, and its age is estimated to be around 13 billion years old. This is indeed an old planet, but whether it is the oldest is difficult to say with certainty. The process of planet formation is still not fully understood, and the universe is vast with many regions that remain unexplored by our current technology.
The age of a planet can be estimated by studying its host star. Stars have a finite lifetime and go through various stages of evolution. By understanding the stage of the star that a planet orbits, astronomers can infer the age of the system. However, this method is not foolproof. There are uncertainties in the measurements and in the models used to interpret the data.
Moreover, the universe is not static. Galaxies and the objects within them are in constant motion. Planets can be ejected from their systems due to gravitational interactions, and they can collide with other celestial bodies. This means that even if we identify an old planet, it might not have remained in the same place since its formation.
The Hubble Space Telescope has been instrumental in measuring the masses of many celestial bodies, including planets. The precision of these measurements can provide insights into the composition and history of these objects. However, the age of a planet is not solely determined by its mass. Other factors, such as its temperature, the presence of an atmosphere, and its orbital characteristics, also play a role.
In conclusion, while the Jupiter-sized planet mentioned in the reference is indeed one of the oldest known planets, claiming it to be the oldest in the universe would be speculative. There may be older planets out there that we have yet to discover, and as our technology and understanding of the cosmos improve, we may one day be able to identify them.

Long before our Sun and Earth ever existed, a Jupiter-sized planet formed around a sun-like star. Now, 13 billion years later, NASA's Hubble Space Telescope has precisely measured the mass of this farthest and oldest known planet.Jul 11, 2003
