A star can appear bright and yet be cold if it is large and emits light predominantly in the infrared spectrum, which is less perceptible to the human eye. For example, a brown dwarf is a type of celestial object that is too low in mass to sustain hydrogen fusion like a typical star but can still emit significant thermal radiation due to its heat. This can make it appear bright in infrared observations while being relatively cool compared to hotter stars. Thus, brightness does not always correlate with temperature, especially when considering different wavelengths of light.

What is a star if you have to explain it to a six year old?
A star is a ball of gas that is very hot and very bright.
Can you give an example of a hot star which is not very bright?
A white dwarf star can be very hot due to residual heat from its earlier evolution, but it may not be very bright because of its small size. This is because the heat energy is spread over a smaller surface area compared to larger, brighter stars.
Why venus is called an evening planet?
Venus is sometimes called "the evening star", although it is a planet. This because it is very bright and always appears close to the Sun in the sky. So, sometimes it appears in the evening as the Sun sets, looking like a very bright star.

What Colour Is A Star That Is Very Cold?
There are no stars that are very cold. Even the "coolest" stars are at thousands of degrees hot; if they weren't capable of supporting nuclear fusion, they would not be stars at all - they would be planets. The "coolest" stars glow a deep red, and are not very bright.
What are the internal characteristics of a Brittle Star?

What is a tiny point that is very bright small far away?
a star
How can a star give off the most light and not be the brightest in the sky?
How bright a star appears depends on both its actual brightness and how far away it is. The farther away a star is, the dimmer it appears. A bright but very distant star many therefore appear dimmer than a less bright star that is closer to us.
What type of symmetry does a brittle star have?
They are very brittle and they can get up to a very bright temperature
