Webb's orbit is not exactly round. NASA created a map to see where Webb is in the Solar System. We were thinking when NASA would create a map to see exactly where Webb is. Well, the US space agency has created one, and as you can see in the picture above, Webb's orbit is not exactly round. 

No way, Webb is a body, not a planet, it moves differently. But if we look at it from a distance, Webb's orbit appears to be almost round or even oval. In any case, Webb works perfectly, being in L2 orbit and moving according to plan. To see exactly where Webb is in the Solar System and to see how its orbit is on L2, go here at section: Webb in 3D Solar System. 

James Webb Telescope reached L2 approx. 5 days ago. Before that, Webb made one last burn correction to go in the right direction to the L2 orbit. Now that we know that Webb is in the right orbit and everything is going according to plan, we are waiting for the first image from Webb and a lot of important information from him about our Universe. NASA has said it will provide new information about Webb on Webb's blog and Where is Webb website. 

In short about Webb's path to L2:

Webb was launched a month ago on December 25, 2021 in Kouru, French Guiana on the Ariane 5 rocket. 33 minutes after its launch, Webb opened its Solar Array, being the first Webb component to unravel from its original state. This was followed by a Mid Course Correction Burn 1a, named by NASA and MCC1a, being the first burn correction to put Webb in the correct orbit. Just one day after its launch, an antenna, the Gimbaled Antenna Assembly, was opened.

Two days after the launch and just one day after the first burn correction, Webb did the second burn correction, which is Mid Course Correction Burn 1b (MCC1b). After Webb was put in the right direction, it widened, unfolding the Forward Sunshield Pallet. And on the same day, Webb opened his Aft Sunshield Pallet.

After the first 4 days since its launch in French Guiana, the telescope made a new opening, more precisely it deployed its Deployable Tower Assembly (DTA). After 5 days of launch, it has unveiled a small and a medium element, Aft Momentum Flap and Sunshield Covers. On the 6th day, Webb started to be as we know it.
He untied two important symmetrical parts: Sunshield PORT Mid-Boom and Sunshield Layer Tensioning Ongoing

It's been 11 days since the launch, with Webb already in 2022. On the 11th day after its launch, it started deploying its Secondary Mirror and finished the process after a few hours. The next day, another important element was unveiled, Aft Deployed Instrument Radiator, this instrument is very sensitive.

13 days after its launch, Webb began unpacking Port Primary Mirror Wing, ending the process after a long day. Two weeks after its launch, it began to deploy another part of it symmetrical to the one opened the day before, meaning that after two weeks it opened its Starboard Primary Mirror Wing. Also two weeks after its launch, Webb is completely DEPLOYED!

On January 12, 2022, just 4 days after it was fully deployed, Webb had to straighten his mirrors. Thus began a process of moving two individual mirrors, also called Individual Mirror Segment Movements, which ended in two hours. Between the 18th and the 28th after the launch, Webb started to lift all 19 mirrors, except for two of them that started to be built later. "Mirror Segment Deployments COMPLETED" announced NASA on the 28th day of Webb's launch. On the 30th day, Webb makes his last burn correction before reaching L2, which is L2 Insertion Burn.
