the object orbits a star
Its gravity makes the object spherical.
The object clears its orbit of other objects.
The criteria that astronomers use to classify an object as a planet is Its gravity makes the object spherical.
There are three principal criteria to determine if an object can be considered a planet:
* It must independently orbit the Sun
* It must have enough mass so that gravity pulls it into a roughly makes it take a spheroidal shape
* It must be large enough to "dominate" its orbit, it must be bigger than any object that crosses it.
The correct answer is: The object orbits a star. Its gravity makes the object spherical. The object clears its orbit of other objects.
The correct answer of the question is : A) Orbits a star, B) Gravity makes spherical and D) Clear orbits of other objects.
The classification of a celestial object to be a planet depends on some parameters.
The most important thing about the planet is that it must clear its orbit. It means it won't share its orbit with other planets. Otherwise, it will be considered as a dwarf planet.
The second thing is that it must move around any stars. The star becomes the centre of that solar system around which planets start revolving in different orbits.
The third thing is that planets are approximately spherical in shape.
The size of the planets does not play a crucial role in the classification of planets. Planets may be smaller than mercury also.
Hence, all the options except the third one are suitable.
The correct answers are: The object orbits a star. Its gravity makes the object spherical. The object clears its orbit of other objects.
According to the current definition of planet, as it is defined by the International Astronomical Union, a planet is a celestial body that fulfills with these three conditions: it orbits around a star, it is massive enough to have a spherical shape due to hydrostatic balance, and it has cleared its orbit of other objects. Around a star there are several kinds of orbiting objects, not all of them are spherical, like asteroids and comets, and while many of them are spherical (like many natural satellites), not all of them have cleared their orbit from the presence of other objects, like the case of Pluto. This definition was made after the debate about whether Pluto was to be considered a planet or not, and astronomers decided to create a new category in which Pluto fits: dwarf planets. These are massive spherical objects in direct orbit around their star that didn't clear up their orbit from the presence of other objects.
"facing the rising sun of our new day begun
let us march on till victory is won.",
because the rising sun is a symbol of hope.
i would say c, admiration because the narrator related to the main character and she, too, once felt ashamed about her culture and wished to be an american girl to impress a boy. she felt admiration because her mom prepared her favorite foods when her and robert's (the guy she liked) family all came together and had a family reunion.
