Stars
Giant balls of hot gas – mostly hydrogen, with some helium and small amounts of other elements
What is what are stars made of?
The Moon’s gravitational pull causes this to occur on Earth, resulting in the rise and fall of ocean levels.
What are tides?
leftover materials clumping together from the Sun’s formation
What is how dwarf planets were formed?
Tens to hundreds of lightyears across
What is how large is a Nebula?
This basic function allows exoplanets to travel in circular or elliptical paths around their host stars.
What is orbiting?
This type of star is characterized by being incredibly hot and large, often hundreds of times the size of the Sun.
What is a supergiant?
The Moon appears to light up at night because it reflects this type of light from the Sun.
What is sunlight?
It’s thin and can be affected by distance from the sun
What is What are dwarf planets atmosphere like?
Emission, reflection, and dark nebulae. Emission nebulae emit light, reflection nebulae reflect nearby light, and dark nebulae do neither, they are black against a starry sky.
What is the three main types of Nebulae?
When exoplanets spin too quickly, this physical effect causes them to bulge at their equator and flatten at their poles.
What is rotation deformation?
This process occurs when gravity causes the gas and dust in a nebula to collapse inward, eventually forming a star.
What is star formation?
This interaction helps stabilize the planet's axial tilt, leading to a more consistent climate over long periods.
What is the gravitational interaction between a planet and its moon?
Looking into large telescopes
What is how scientists find new dwarf planets?
A giant cloud of dust and gas in space that helps form stars.
What is the main function of a Nebulae?
This vital function of an exoplanet's atmosphere helps trap heat from its star, making the planet warm enough to potentially support life.
What is heat retention?
Nuclear fusion begins When the temperature at a protostar's core reaches this degree.
What is 10 million degrees Celsius?
Moons orbit planets due to this force, which attracts them toward the planet’s center of mass.
What is gravity?
It spins faster, by far, than anything else of its size, whirling on its axis in only four hours.
What is the reason why some dwarf planets are oddly shaped?
This space telescope, launched in 1990, has provided some of the most detailed images of nebulae by observing them in visible light.
What is the Hubble Space Telescope?
Larger exoplanets perform this function more strongly than smaller ones, helping them maintain their spherical shape and hold onto their atmospheres.
What is gravitational pull?
O, B, A, F, G, K and M
What are the seven letters that characterize the seven main types of stars?
Moons contribute to the formation of planetary rings by preventing this process, which keeps debris in orbit around a planet.
What is accretion?
This is the name of the most well-known dwarf planet in the Kuiper Belt, once considered the ninth planet in our solar system.
What is Pluto?
Gravity causes the gas and dust in a nebula to do this, leading to the formation of stars and planetary systems.
What is collapse?
This function of exoplanets creates day and night cycles as they spin, similar to Earth's 24-hour rotation.
What is axial rotation?
