The mass of a quark star can vary depending on its size and composition. Quark stars are hypothetical celestial objects composed primarily of quarks, which are elementary particles and fundamental constituents of matter. They are thought to form under extreme conditions, such as during the collapse of a massive star.
The exact mass of a quark star is uncertain because quark stars are still theoretical and have not been observed directly. However, there are several theoretical models that predict a wide range of possible masses for quark stars.
Some models suggest that quark stars could have masses similar to neutron stars, which typically range from about 1.4 to 2 times the mass of the Sun (Solar masses). Other models propose that quark stars could have much higher masses, potentially reaching several times the mass of the Sun.
It's important to note that quark stars are still a topic of active research, and more studies and observations are needed to provide a more definitive answer regarding their properties, including their mass.
