Ni khat kan tih hi kan chenna khawvel planet-in a awmna axis-a a vir chhuah rei zawng hi a ni a, vawi khat a vir chhuah rei zawng hi darkar 24 emaw second 86,400 a ni. A hun duh rei zawng hi ni leh thla leh lei magnetic field avangin a danglam ve hret thin bawk. 

Hun hmasa lamah chuan kan chenna khawvel planet Earth hi a axis-ah a vir chak hle a, chuvangin ni khat pawh a rei lo hle a, darkar 19 lek ni-a ngaih a ni. Hetiang a nihna chhan chu thlain khawvel a hnaih a, khawvel a pawh nat em vang a ni. Tun hma aiin tunah chuan thla hian khawvel a hlat ta hle a,  khawvel hi a vir muang ta a, ni khat pawh a lo rei ta zawk a ni. 

Kum 2020-ah khan scientist-ten kan chenna khawvel hi a axis-ah a inher chak leh ta deuh tih an hmu chhuak a,  kum 1970 hnu lamah a inher chak ber tum a ni an ti hial. 

A vir chak ber ni leh ni rei loh ni bera an lo record tawh chu July 5, 2024 kha a ni a, a pangngai aiin 1.65 miiliseconds laiin a vir chak niin an chhinchhiah.
