Dunes in a desert are constantly changing shape due to the wind.
They are not star-shaped. Stars are actually spherical due to gravity.
"Dunees" is not a commonly recognized term. If you are referring to "dunes," then yes, dunes typically form in areas where sand is abundant, such as deserts, beaches, and sandy shorelines, due to the wind and water movements that shape them over time.
The largest sand dunes in the world are found in the Namib Desert in Namibia, specifically in the Sossusvlei area. These dunes, known as "star dunes," can reach heights of over 1,000 feet (about 300 meters). Dune 7, one of the tallest in the region, is often cited as the highest accessible dune for visitors. The striking red color of the dunes is due to the iron oxide present in the sand.
Mostly hydrogen, helium is also present due to fusion.
A barchan dune has a crescent shape with horns pointing downwind and forms in areas with limited sand, while a parabolic dune has a U-shape with the horns pointing upwind and forms in areas with abundant sand. Additionally, barchan dunes are individual and migrate due to wind direction, while parabolic dunes are stationary and often found in coastal regions.
No, due to the shape of the earth you can not see the North Star below the equator.
Earth is an oblate spheroid, meaning it is mostly spherical in shape but slightly flattened at the poles and bulging at the equator due to its rotation.

Sand dunes can continue to change over years due to factors such as wind erosion, deposition of sand by shifting winds, vegetation growth and decay, and human activities like recreation and development. These processes can cause the dunes to shift in shape and size, or even lead to their stabilization if vegetation takes root and helps hold the sand in place.
A star theater planetarium can mostly only be found online due to its rareness and uniqueness. These products usually range in price from around $170 to about $250.
The sun is a ball-shaped star. It appears as a circle in the sky due to its distance from Earth, but it is a spherical object like other stars in the universe.
