Michel Mayor and Didier Queloz discovered 51 Pegasi B on October 6, 1995, at the Observatoire de Haute-Provence in Southeast France.

Since its discovery, there have been thousands of additional exoplanets found, demonstrating that the universe is much more vast and fascinating than we ever imagined.

FAQ

1. What is 51 Pegasi b?

51 Pegasi b is an exoplanet, meaning it is a planet that orbits a star other than our Sun. It was the first exoplanet to be discovered orbiting a main-sequence star, and it is located approximately 50 light-years away from Earth in the constellation Pegasus. The planet is a gas giant, similar in size to Jupiter, but with a much shorter orbital period of just 4.2 Earth days.

2. Who discovered 51 Pegasi b?

51 Pegasi b was discovered by Swiss astronomers Michel Mayor and Didier Queloz in 1995. They used the radial velocity method, which involves measuring the wobble of a star caused by the gravitational pull of an orbiting planet. The discovery of 51 Pegasi b was a breakthrough in the field of exoplanet research, and it opened up new possibilities for studying the formation and evolution of planetary systems.

3. What is the temperature of 51 Pegasi b?

Due to its close proximity to its host star, 51 Pegasi b has a surface temperature of approximately 1200 degrees Celsius (2200 degrees Fahrenheit). This extreme temperature is hot enough to melt metal, and it is much hotter than any planet in our Solar System. The high temperature is caused by the planet’s close proximity to its star, which results in intense radiation and heat.

4. Is 51 Pegasi b habitable?

No, 51 Pegasi b is not habitable. The extreme temperatures and harsh conditions on the planet make it unsuitable for life as we know it. However, the discovery of exoplanets like 51 Pegasi b has led to a greater understanding of the diversity of planetary systems in our galaxy, and it has sparked new interest in the search for habitable exoplanets that could potentially support life.
