‘Perihelion’: Earth closest to sun

On January 3, the Earth will be at closest to the sun in a phenomenon called ‘Perihelion’.

At 11.05 am on January 3rd, the earth will be at the closest point to the sun in its annual elliptical orbit, at a distance of 14,70,97,237 km approximately.

What you need to know?

Perihelion is an important event for research and educational purposes although the public cannot observe it.

Commonly it is believed that the distance of the earth from the sun decides the season or temperature on the earth. But this is not true.

The axial tilt (approx. 23.5 degrees) of the earth on its axis while revolving around the Sun regulates seasons on the earth with one of the hemispheres facing away or towards the Sun.

So, while the earth is closest to Sun this time in January, it is winter in India and countries in Northern Hemisphere, it is summer in the Southern Hemisphere.

On July 6, the earth will be at ‘Aphelion’ at 15,20,95,571 km from the sun, i.e. it will be at the farthest point from the sun.

Species we lost in 2017 and the ones that managed to hold on

According to the updated IUCN (International Union for Conservation of Nature) red list, here are the species that were marked as “EXTINCT”:

Christmas Island Pipistrelle : This small bat found exclusively on Christmas Island, Australia was listed as critically endangered last year. Predation, loss of habitat, and diseases were pointed out as causes for its extinction.

Christmas Island Whiptail-skink : Another species endemic to Christmas Island, this lizard went extinct this year. Non-native predators and insecticide poisoning drove it over the edge.

Christmas Island chained gekho : The species is listed as extinct in the wild, which means it is now found only in a captive breeding programme.

Gunthers Dwarf Burrowing skink : Though no record of the skink has been made for more than 125 years, this native of South Africa was officially confirmed to be extinct only this year.
