What time can I see the comet?
Space and AstronomyComet Leonard is 2021’s best comet Comet C/2021 A1 (Leonard) – 2021’s best and brightest comet – is now in the evening sky for Northern Hemisphere observers. We heard on December 15, and again around December 19-20, that the comet had brightened more than expected. What time will the Neowise comet be visible? Comet NEOWISE

What are the four planets that follow the asteroid belt called?
Space and AstronomyThe planets inside the asteroid belt are termed the Inner Planets (or the Terrestrial Planets): Mercury, Venus, Earth, and Mars. The planets outside the asteroid belt are termed the Outer Planets: Jupiter, Saturn, Uranus, Neptune, and Pluto. What are the four planets beyond the asteroid belt? Beyond the asteroid belt lie the outer planets, also

What are the quadrant angles?
Space and AstronomyDefinition A quadrantal angle is an angle in standard position whose terminal ray lies along one of the axes. Examples of quadrantal angles include, 0, π/2 , π , and 3π/ 2. Angles coterminal with these angles are, of course, also quadrantal. How do you find the angle of a quadrant? Video quote: And so

What does a supplementary angle look like?
Space and AstronomySupplementary angles are two angles whose measures add up to 180° . The two angles of a linear pair , like ∠1 and ∠2 in the figure below, are always supplementary. But, two angles need not be adjacent to be supplementary. In the next figure, ∠3 and ∠4 are supplementary, because their measures add to

What’s in the interstellar medium?
Space and AstronomyIn a nutshell, the interstellar medium is the material that fills the space between stars. 99% of the interstellar medium is made up of (mostly hydrogen) gas and the rest is composed of dust. The interstellar medium is vast and expansive in size but very, very low in density. What are the four components of

Why does Mercury have less gravity?
Space and AstronomySince Mercury has less mass than Earth, the surface gravity on Mercury is less than the surface gravity on Earth. The surface gravity on Mercury is only about 38% of the surface gravity on Earth, so if you weigh 100 pounds on Earth, you would weigh only 38 pounds on Mercury. Does Mercury have the

What are the parts of a sundial?
Space and AstronomyAlmost every sundial has two basic parts: the pointer and the dial. The pointer, also called a style or gnomon, casts a shadow, indicating the time of day. The numbered dial is the area in which the shadow falls, showing the hour. What are the main parts of a sundial and how do they work?

How far as a percentage does the radiative zone extend to the photosphere?
Space and AstronomyAbove the core is a region known as the radiative zone—named for the primary mode of transporting energy across it. This region starts at about 25% of the distance to the solar surface and extends up to about 70% of the way to the surface. How far does the radiation zone extend? The radiative zone

Why was the international space station built?
Space and AstronomyPurpose. The ISS was originally intended to be a laboratory, observatory, and factory while providing transportation, maintenance, and a low Earth orbit staging base for possible future missions to the Moon, Mars, and asteroids. What is the main purpose of the International Space Station? The primary objective of the ISS is to support scientific research
