E899

E899 is a designation that can refer to several different entities, most notably an astronomical object and a chemical compound.

In astronomy, E899 is a comet. It was discovered by the LINEAR survey in 2000. Comets are icy bodies that release gas or dust. E899 is a periodic comet, meaning it follows an orbit that brings it back into the inner solar system relatively regularly. Its orbital period is approximately 5.5 years. Like other comets, its appearance changes as it approaches the Sun, developing a coma and sometimes a tail.

As a chemical compound, E899 refers to N-(2-amino-5-ethyl-4-methylphenyl)-2-ethoxybenzamide. This is an organic molecule. Its specific applications and properties are generally found in scientific literature related to organic chemistry and potentially in materials science or pharmaceuticals, depending on its intended use. Detailed information about its synthesis, reactivity, and applications would typically be found in specialized chemical databases and research papers.
