Stars are luminous bodies made up of Hydrogen and some Helium which are so large the gravitational attraction has pushed the Hydrogen atoms so close together that they fuse into Helium converting a lot of mass into energy.
Planets are not as big, some are rocky some gaseous.

How many stars does earth have?
Earth is a planet, not a star. The Sun is the star at the center of our solar system.
Is the sun a terrestrial planet?
No, the sun is not a terrestrial planet. It is a star, a massive ball of plasma that generates energy through nuclear fusion. Terrestrial planets, like Earth, are small, rocky planets that orbit the sun.
How are planets near other stars found?
There are several ways, the most popular are: 1) Just like a star affects the motion of a planet so does the planet affect the motion of the star, but only in small degree. Astronomers look at stars and see if they have a periodic shift in their movement and conclude that a planet is causing it. 2) If the orbit of a planet is "edge on", then it will eclipse the star and cause a periodic reduction of its light by up to 2%.
Is it true that an average star spends 90 percent of its life as a helium burning main sequence star?
Yes, it is true that an average star spends about 90 percent of its life on the main sequence burning hydrogen into helium through nuclear fusion. This is the longest and most stable phase in a star's life cycle before it transitions into the next phase.
What is difference between apparent brightness and absolute brightness?
Absolute Brightness: How bright a star appears at a certain distance. Apparent Brightness: The brightness of a star as seen from Earth.
What are the main difference between a planet and a star?
Our Earth is an example of a planet, whilst our Sun is an example of a star.
How would you explain to someone the difference between a planet and a star?
The planet reflects solar light and a star has its own light.
What is the main diffidence between a star and a planet?
What is the milky way
What is the difference between sun and comet and planet?
Basically, Earth is a planet, the Sun is a star, and a comet is an icy small body of ice.
What is the difference between the moon earth and sun?
Earth is a Planet. Moon is a satalite. Sun is a meduim sized star.
What is the difference in a star than a planet?
a star is way bigger than a planet. you need a telescope to see some of the planets.a star twinkles.a planet glows.
Which quality defines a planet?
A planet is a ruffly spherical object that orbits a star. The difference between a planet and a dwarf planet is a planet clears its orbit of debris by itself- a dwarf planet has help! Hope this helps!xxx :-)
What is difference between intermediate mass star and main sequence stars?
i don't think so
The main difference between the nebular and condensation theories is that the condensation theory stresses the importance of to the formation of planets.?
The main difference between the nebular and condensation theories is their emphasis on different aspects of planet formation. Nebular theory focuses on the collapse of a rotating nebula to form a star and planets, while condensation theory emphasizes the role of solid particles (dust and gas) in the early stages of planet formation.
What type of celestial object does your planet orbit?
My planet orbits a star known as the Sun, which is a G-type main-sequence star.
Is the Sun a star a planet or a nebula?
The Sun is a star, specifically a G-type main-sequence star, which is the star at the center of our solar system. It is not a planet or a nebula.
What is different between a star and a planet?
A Star converts hydrogen into energy by nuclear fusion. A planet does not
