Atropos (minor planet designation: 273 Atropos) is a typical Main belt asteroid that was discovered by Austrian astronomer Johann Palisa on 8 March 1888 in Vienna.
Photometric observations of this asteroid at the Palmer Divide Observatory in Colorado Springs, Colorado, in 2007 gave a light curve with a period of 23.852 ± 0.003 hours and a brightness variation of 0.60 ± 0.03 in magnitude.[3]

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
